Isoionic point firelock provided by the invention, follows following rule to the switch control of DC voltage unit: need to open a direct current unit time, always open time in closed condition that DC voltage unit at most; Need to close a DC voltage unit time, always close time in opening that DC voltage unit at most.Such switch control law brings two benefits: (1) each switch module operating time region equalization, equivalent load equilibrium; (2), to certain clock pulse frequency, the switching frequency of the electronic switch of each DC voltage unit significantly reduces.Taking DC reference signal as example, if clock pulse frequency is f, high voltage source is made up of n DC voltage unit, and the actual switch frequency of each DC voltage unit electronic switch is f/n.
In the present invention, in high voltage source, introduce fly-wheel diode, the electronic switch of each DC voltage unit can independently be controlled, without while conducting or cut-off.When the electronic switch conducting of certain direct current unit, its output voltage is series connection access; When electronic switch cut-off, other direct current unit is by the outside circuit output voltage of fly-wheel diode (electric current), i.e. the effect of fly-wheel diode is the cut-off state at electronic switch, and current path is provided.The effect of afterflow coil is to suppress electronic switch conducting or the transient state impulse disturbances of cut-off moment; On the other hand, the equivalent self inductance coefficient of all afterflow coils, also participates in forming rear class filter circuit.
The circuit structure of the second high-voltage DC power supply in high-voltage radio-frequency power supply 16 and the course of work and the one the second high-voltage DC power supplies are similar, the second high-voltage DC power supply comprises m level DC voltage unit, each DC voltage unit is by the cascade of afterflow coil, control system 6 can the each DC voltage unit of Long-distance Control break-make apply required direct current energy to interior electrode and external electrode, described m is greater than or equal to 4 integer.M can equate with n, according to design.
Because high-voltage DC power supply provided by the invention and high-voltage radio-frequency power supply can be by controller software its output any voltage values of programming, so the flame temperature of isoionic point firelock can be set as required.Form by multi-stage cascade and produce high-tension DC power supply, therefore can adopt the components and parts that withstand voltage is lower to complete low-voltage to high-tension conversion.
In addition, CMOS pipe can use the electronic switches such as transistor, controllable silicon to replace.
Fig. 5 is the schematic diagram of the in vitro burning torch cooling system of grade provided by the invention.As shown in Figure 5, described cooling system comprises main pump 23, auxiliary pump 24, three-way valve 20 and heat-exchange system, main pump 23 drives cooling water to flow into the first end of three-way valve 20, and after flow into the water inlet pipe 17 of external electrode through the second end of three-way valve 20, cooling water heating in external electrode 2 is then flowed out from outlet pipe 18, cooling water is also through the 3rd end of three-way valve 20 heat-exchange system 19 of flowing through, and described heat-exchange system 19 is condenser.Outlet pipe 18 is provided with leaving water temperature transducer 21 to detect coolant-temperature gage, if leaving water temperature, lower than lower limit, regulates three-way valve 20, heat-exchange system flow is reduced; Temperature, higher than the upper limit, regulates three-way valve, and heat-exchange system flow is increased.Described lower limit and higher limit are artificially set according to the performance requirement of plasma electrode.The oral siphon place of described three-way valve 20 is provided with hydraulic pressure sensor 22 to detect cooling water flow, if flow is normal, keeps main pump 23 to work; If flow is undesired, enable auxiliary pump 24.The oral siphon place of main pump 23 branch roads is provided with isolating valve 31 and the cleaner 29 for filtrating impurity in water, and outlet pipe place is provided with safety valve 25 and isolating valve 27, and the object that isolating valve 31 and 29 is set is the unimpeded of cooling water keep cooling system in the time of maintenance main pump 23 in.Safety valve 25 is the pressure for regulating cooling system water.The oral siphon place of auxiliary pump 24 branch roads is provided with isolating valve 32 and the cleaner 30 for filtrating impurity in water, and outlet pipe place is provided with safety valve 26 and isolating valve 28.The object that isolating valve 32 and 28 is set is the unimpeded of cooling water keep cooling system in the time of maintenance auxiliary pump 24 in.Safety valve 26 is the pressure for regulating cooling system water.In cooling system, be also provided with micro-hydraulic pressure and regulate branch road, micro-hydraulic pressure regulates branch road to comprise airtight container 36, water compensating valve 33 and 34 and safety valve 35, and the center of airtight container 36 is provided with swelling gasbag 37.In swelling gasbag 37, the pressure of gas is set as required, when in airtight container 36, the pressure of water equates with the pressure of gas in swelling gasbag 37, the volume of swelling gasbag 37 remains unchanged, when in airtight container 36, the pressure of water reduces, swelling gasbag 37 expands, gas pressure reduces, add injection cooling water by water compensating valve 33 or 34 to cooling system, when in airtight container 36, the pressure of water increases, swelling gasbag 37 volume-diminished, gas pressure increases, and safety valve 35,25 and 26 discharges gas, and the pressure in cooling system is reduced.So keep the constant pressure of cooling system.
