Description
技术领域technical field
本发明涉及一种实现全压双极性控制的开关磁阻电机功率拓扑结构，属于电机制造与控制技术。The invention relates to a power topology structure of a switched reluctance motor for realizing full-voltage bipolar control, which belongs to the motor manufacturing and control technology.
背景技术Background technique
随着电力电子器件技术、微电子技术和自动控制技术的发展，尤其是稀土永磁材料出口限制所引起的价格上涨，开关磁阻电机的应用将越来越广泛。另一方面，在一些深空、深海、昼夜温差大的特殊作业环境下，永磁体的磁性能不稳定，不利于永磁电机在上述领域的应用。而开关磁阻电机作为一种电励磁电机，其定转子均由普通硅钢片压叠制成双凸极结构，转子上既无永磁体也无绕组，定子上只有集中式绕组线圈，依据“磁阻最小”原理工作。开关磁阻电机制造简单、成本低、结构牢靠、体积小、重量轻、散热方便。在工业调速系统领域中已显示出强大的竞争力，在电动汽车、家用电器、纺织机械、电气传动等方面也有广阔的前景。然而，限制开关磁阻电机调速系统进一步推广应用的一个重要技术瓶颈如图1所示，现有三相开关磁阻电机的不对称桥式功率变换器拓扑每相绕组采用两个主开关、两个缓流二极管，比普通三相异步电机功率变换器多了六个电力缓流二极管。因此，增加了开关磁阻电机功率变换器的复杂性和成本。此外，开关磁阻电机功率变换器尚无一个统一的标准，无法大规模生产，这些都大大增加了开关磁阻电机功率变换器的开发成本与硬件成本。近年来，有学者提出如图2所示的功率拓扑变换器来代替不对称桥式功率变换器，解决了传统三相开关磁阻电机不对称桥式功率变换器功率拓扑结构复杂、成本高、无统一标准和无法大规模生产的缺点。然而，采用图2所示的功率拓扑结构控制开关磁阻电机亦会带来另外一些缺点，例如只可以加载一半母线电压至开关磁阻电机的每相绕组上，导致电流上升率di/dt变小、速度响应受限制、过载能力差、效率低等缺点。With the development of power electronic device technology, microelectronic technology and automatic control technology, especially the price increase caused by the export restrictions of rare earth permanent magnet materials, the application of switched reluctance motors will become more and more extensive. On the other hand, in some special operating environments such as deep space, deep sea, and large temperature difference between day and night, the magnetic properties of permanent magnets are unstable, which is not conducive to the application of permanent magnet motors in the above fields. The switched reluctance motor is an electric excitation motor, its stator and rotor are laminated with ordinary silicon steel sheets to form a double salient pole structure, there is neither permanent magnet nor winding on the rotor, only concentrated winding coils on the stator, according to the "magnetic The principle of least resistance works. The switched reluctance motor is simple to manufacture, low in cost, reliable in structure, small in size, light in weight, and convenient in heat dissipation. It has shown strong competitiveness in the field of industrial speed control systems, and has broad prospects in electric vehicles, household appliances, textile machinery, and electrical transmission. However, an important technical bottleneck that limits the further popularization and application of SRM speed control systems is shown in Figure 1. The current asymmetric bridge power converter topology for three-phase SRMs uses two main switches and There are six slow-flow diodes, which are six more power slow-flow diodes than ordinary three-phase asynchronous motor power converters. Therefore, the complexity and cost of the switched reluctance machine power converter is increased. In addition, there is no uniform standard for the power converter of the switched reluctance motor, and it cannot be mass-produced, which greatly increases the development cost and hardware cost of the power converter of the switched reluctance motor. In recent years, some scholars have proposed a power topology converter as shown in Figure 2 to replace the asymmetric bridge power converter, which solves the problem of complex power topology, high cost and There are no uniform standards and the disadvantages of being unable to produce on a large scale. However, using the power topology shown in Figure 2 to control the SRM will also bring some other disadvantages. For example, only half of the bus voltage can be applied to each phase winding of the SRM, resulting in a change in the current rise rate di/dt Small size, limited speed response, poor overload capacity, low efficiency and other shortcomings.

如图3所示为一种实现全压双极性控制的开关磁阻电机功率拓扑结构，包括直流电源V、电源滤波电容C、8个功率开关管S1、S2、S3、S4、S5、S6、S7、S8和一个三相开关磁阻电机SRM；直流供电电源V的正极同时连接功率开关管S1、S2、S3、S4的集电极，供电电源V的负极同时连接功率开关管S5、S6、S7、S8的发射极，电源滤波电容C并联连接在供电电源V的正负两极，开关磁阻电机SRM的A相绕组一端同时连接在功率开关管S1的发射极和功率开关管S5的集电极，开关磁阻电机SRM的A相绕组另一端同时连接在功率开关管S4的发射极和功率开关管S8的集电极；开关磁阻电机SRM的B相绕组一端同时连接在功率开关管S2的发射极和功率开关管S6的集电极，开关磁阻电机SRM的B相绕组另一端同时连接在功率开关管S4的发射极和功率开关管S8的集电极；开关磁阻电机SRM的C相绕组一端同时连接功率开关管S3的发射极和功率开关管S7的集电极，开关磁阻电机SRM的C相绕组另一端同时连接在功率开关管S4的发射极和功率开关管S8的集电极。As shown in Figure 3, it is a switched reluctance motor power topology that realizes full-voltage bipolar control, including DC power supply V, power supply filter capacitor C, and 8 power switch tubes S1, S2, S3, S4, S5, and S6 . The emitters of S7 and S8, the power supply filter capacitor C are connected in parallel to the positive and negative poles of the power supply V, and one end of the A-phase winding of the switched reluctance motor SRM is connected to the emitter of the power switch S1 and the collector of the power switch S5 at the same time The other end of the A-phase winding of the switched reluctance motor SRM is connected to the emitter of the power switch S4 and the collector of the power switch S8 at the same time; one end of the B-phase winding of the switched reluctance motor SRM is connected to the emitter of the power switch S2 at the same time pole and the collector of the power switch tube S6, the other end of the B-phase winding of the switched reluctance motor SRM is connected to the emitter of the power switch tube S4 and the collector of the power switch tube S8 at the same time; one end of the C-phase winding of the switched reluctance motor SRM The emitter of the power switch S3 and the collector of the power switch S7 are simultaneously connected, and the other end of the C-phase winding of the switched reluctance motor SRM is simultaneously connected to the emitter of the power switch S4 and the collector of the power switch S8.
上述开关磁阻电机功率拓扑结构的工作原理是：开关磁阻电机SRM由双极性电流供电，即通过开关磁阻电机SRM绕组的励磁电流即可以为正亦可以为负。与传统的不对称桥式功率拓扑结构相比，本案结构亦可以反向励磁。The working principle of the above switched reluctance motor power topology is: the switched reluctance motor SRM is powered by bipolar current, that is, the excitation current passing through the switched reluctance motor SRM winding can be either positive or negative. Compared with the traditional asymmetric bridge power topology, the structure of this case can also be reverse-excited.
当功率开关管S1、S8导通时，开关磁阻电机SRM的A相绕组正向励磁，电流流向如图4所示。当功率开关管S1、S8关断时，开关磁阻电机SRM的A相绕组电路如图5所示。当功率开关管S4、S5导通时，开关磁阻电机SRM的A相绕组反向励磁，电流流向如图6所示，此时电流方向与正向励磁时电流流向相反。When the power switch tubes S1 and S8 are turned on, the A-phase winding of the switched reluctance motor SRM is positively excited, and the current flow direction is shown in FIG. 4 . When the power switch tubes S1 and S8 are turned off, the A-phase winding circuit of the switched reluctance motor SRM is shown in FIG. 5 . When the power switch tubes S4 and S5 are turned on, the A-phase winding of the switched reluctance motor SRM is reversely excited, and the current flow direction is shown in Figure 6. At this time, the current direction is opposite to that of the forward excitation.
当功率开关管S2、S8导通时，开关磁阻电机SRM的B相绕组正向励磁，电流流向如图7所示。当功率开关管S2、S8关断时，开关磁阻电机SRM的B相绕组电路如图8所示。当功率开关管S4、S6导通时，开关磁阻电机SRM的B相绕组反向励磁，电流流向如图9所示，此时电流方向与正向励磁时电流流向相反。When the power switch tubes S2 and S8 are turned on, the B-phase winding of the switched reluctance motor SRM is positively excited, and the current flow direction is shown in FIG. 7 . When the power switch tubes S2 and S8 are turned off, the B-phase winding circuit of the switched reluctance motor SRM is shown in FIG. 8 . When the power switch tubes S4 and S6 are turned on, the B-phase winding of the switched reluctance motor SRM is reversely excited, and the current flow direction is shown in Figure 9, and the current direction at this time is opposite to that of the forward excitation.
当功率开关管S3、S8导通时，开关磁阻电机SRM的C相绕组正向励磁，电流流向如图10所示。当功率开关管S3、S8关断时，开关磁阻电机SRM的C相绕组电路如图11所示。当功率开关管S4、S7导通时，开关磁阻电机SRM的C相绕组反向励磁，电流流向如图12所示，此时电流方向与正向励磁时电流流向相反。When the power switch tubes S3 and S8 are turned on, the C-phase winding of the switched reluctance motor SRM is positively excited, and the current flow direction is shown in FIG. 10 . When the power switch tubes S3 and S8 are turned off, the C-phase winding circuit of the switched reluctance motor SRM is shown in FIG. 11 . When the power switch tubes S4 and S7 are turned on, the C-phase winding of the switched reluctance motor SRM is reversely excited, and the current flow direction is shown in Figure 12. At this time, the current direction is opposite to that of the forward excitation.
本案亦可以用于四相开关磁阻电机，此时电机的接线如图13所示，需要说明的是此时开关磁阻电机SRM也运行在双极性电流下，但每相绕组电压只有直流电压源V的一半。当电机工作时有两相绕组通电且电流极性相反，每两相绕组轮流进行励磁，绕组励磁的顺序为A+B->B-C+>C+D->D-A+>A+B->B-C+>C+D->D-A+….This case can also be used for a four-phase switched reluctance motor. At this time, the wiring of the motor is shown in Figure 13. It should be noted that the switched reluctance motor SRM also operates under bipolar current, but the winding voltage of each phase is only DC. half of the voltage source V. When the motor is working, two-phase windings are energized and the current polarity is opposite, and each two-phase winding is excited in turn. The order of winding excitation is A+B->B-C+>C+D->D-A+>A+B- >B-C+>C+D->D-A+….
当S1、S5所在桥臂，S2、S6所在桥臂，S3、S7所在桥臂，S4、S8所在桥臂中任何一桥臂放生故障时，电机可利用余下三个桥臂工作在三相半压双极性控制下工作，如图14所示。When any of the bridge arms where S1 and S5 are located, the bridge arms where S2 and S6 are located, the bridge arms where S3 and S7 are located, and the bridge arms where S4 and S8 are located, the motor can use the remaining three bridge arms to work in three-phase and a half work under bipolar control, as shown in Figure 14.
使用如图3所示的一种可以实现全压双极性控制的开关磁阻电机功率拓扑，可以代替原来三相桥式功率拓扑结构，使基于双极性控制的开关磁阻电机功率变换器可以实现加载母线电压全压至每相绕组上，与图2所示的三相桥式电路相比具有更好的性能，同时由于市场上单相桥臂已实现大规模化生产，与如图1所示的传统不对称桥式功率拓扑相比，具有更低的成本优势。本案的全压双极性控制的开关磁阻电机功率拓扑亦可以用于四相开关磁阻电机的半压双极性控制，具有高度灵活性和多功能性。此外，当本案的功率变换器任一桥臂发生故障时，利用余下的三个桥臂可以实现三相半压双极性控制，具有高可靠性。本发明思想必将进一步推动开关磁阻电机在调速驱动系统中的应用，提高其市场竞争力。Using a switched reluctance motor power topology that can realize full-voltage bipolar control as shown in Figure 3 can replace the original three-phase bridge power topology, and make the power converter of switched reluctance motor based on bipolar control It can realize the full voltage loading of the busbar voltage to each phase winding, which has better performance compared with the three-phase bridge circuit shown in Figure 2. At the same time, since the single-phase bridge arm on the market has achieved large-scale production, it is similar to the three-phase bridge circuit shown in Figure 2. Compared with the traditional asymmetric bridge power topology shown in 1, it has a lower cost advantage. The switched reluctance motor power topology with full-voltage bipolar control in this case can also be used for half-voltage bipolar control of four-phase switched reluctance motors, which has high flexibility and versatility. In addition, when any bridge arm of the power converter in this case fails, the three-phase half-voltage bipolar control can be realized by using the remaining three bridge arms, which has high reliability. The idea of the invention will further promote the application of the switched reluctance motor in the speed-regulating drive system and improve its market competitiveness.
以上所述仅是本发明的优选实施方式，应当指出：对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications are also possible. It should be regarded as the protection scope of the present invention.
