Description
Technical field
The present invention relates to Motor Control Field, be specifically related to a kind of electric machine controller.
Background technology
The electric bicycle of state's inner control three-phase direct-current brushless motor and the controller architecture of battery-operated motor cycle are as shown in Figure 1, mainly comprise power source conversion, various input/output interface, single-chip microcomputer (MCU), pre-driver part, reach the high-power driving part of forming by mos field effect transistor (Metal-Oxide-SemiconductorField-Effect Transistor is called for short MOSFET or metal-oxide-semiconductor).And motor has U, V, W three-phase, and this has just determined to have at least 6 metal-oxide-semiconductors to control motor, includes 6 metal-oxide-semiconductors in the electric vehicle motor controller at least.
The electric vehicle motor controller of market sale now, the power source conversion of its main control part, MCU, input/output interface, pre-driver part and metal-oxide-semiconductor all are unified on the printed circuit board.Metal-oxide-semiconductor can produce bigger heat when work, so must consider its heat dissipation problem.Manufacturer all helps its heat radiation by the aluminum shell of controller now.In conjunction with the drive principle of Electric Machine Control, when printed circuit board layout, all 6 metal-oxide-semiconductors are yi word pattern usually and arrange, be positioned at the plate end of printed circuit board (PCB).With the 250W controller is example, as shown in Figure 2, adopts metal-oxide-semiconductor and MCU and pre-driver to be integrated, the upright welding of 90 degree, the fundamental of practical products such as heating panel closely contacts with aluminum alloy casing, has reached the metal-oxide-semiconductor heat radiation more effectively, and the firm and production cost of shell is low.
There is following drawback in this kind mode:
1, controller is in work under the severe jolt environment throughout the year, because metal-oxide-semiconductor becomes continuing firmly of the 90 vertical welding of degree with pcb board, and metal-oxide-semiconductor is fastened on the aluminum alloy casing for heat radiation, from the mechanical structure angle, becoming the mechanical stress of 90 degree both directions to be easy to make the weld part generation metal fatigue that continues firmly to cause cracking, is to produce to burn one of major reason of metal-oxide-semiconductor and pcb board.
2, in the fault of electric motor car, having is that metal-oxide-semiconductor burns greatly, and the high temperature that produces when it burns can also burn control circuit board in the lump, thereby control circuit board is scrapped thereupon.During maintenance, can only change the monoblock control circuit board, maintenance cost is higher.
3, the 2nd pin of each metal-oxide-semiconductor and the 3rd pin all will bear electric current more than the 12A-35A in conducting moment maximum in the controller, are referred to as big electric current pin.Because of the flow of maximum current is directly proportional with sectional area of wire, and the spacing of the 2nd pin of metal-oxide-semiconductor and the 3rd pin has only 2.5 millimeters, the pin portion wiring that is to say PCB is limited in the thick 0.035 millimeter * double sided board of 1.5 millimeters * pcb board of live width Copper Foil=0.105 square millimeter, and the safety margins electric current of the Design Theory of this area has only 3 amperes.Therefore can only solve by the rough method that pin and PCB weld part are thickeied scolding tin during actual production.The thing followed is exactly that the welding of metal-oxide-semiconductor pin needs manual operations, be difficult to during manual welding guarantee that solder thickness is even, cause controller that the metal-oxide-semiconductor weld part can often take place thus and when operation, produce high temperature and burnt, and even pcb board is breakdown burns, cause the The whole control blackboard newspaper useless.
4, according to foregoing description, controller must have 6 metal-oxide-semiconductors at least, and will strengthen the power output of controller, and existing practice majority is that the quantity by corresponding increase metal-oxide-semiconductor realizes.Because of motor has U, V, W three-phase, so the quantity of the metal-oxide-semiconductor that increases is necessary for 3 multiple.According to the drive principle of Electric Machine Control, require the last bridge metal-oxide-semiconductor of the same phase of control to need to place nearby with following bridge metal-oxide-semiconductor.In conjunction with the heat radiation requirement, when printed circuit board layout, the existing practice is that all metal-oxide-semiconductors are in one line, is positioned at the plate end of printed circuit board (PCB).Desire is put into these metal-oxide-semiconductors, can only increase the length of printed circuit board (PCB) under above-mentioned theory.Basic money on the market is the controller of 6 metal-oxide-semiconductors, its length is generally 80-100mm, as shown in Figure 3, and the metal-oxide-semiconductor in the controller to be increased to 12, its controller length is generally at 180-200mm, as shown in Figure 4, increased the length of printed circuit board (PCB) certainly will will increase simultaneously the length of aluminum shell.So, production cost also significantly increases thereupon.
