Because the IGBT power transistor has the characteristic of switching at a high speed, waveform is influential greatly to the induction coefficient of distribution when ON/OFF, diode and electric capacity should be tried one's best near the IGBT power transistor, distribution also should be short more good more in the middle of input wiring and the IGBT, and the control utmost point holding wire of IGBT needs careful assembling.
What deserves to be mentioned is that this device is different from the traditional frequency conversion device, because most of frequency converter is to adopt the similar signal of the sinusoidal wave range of linearity to promote, and then the speed of control alternating current machine, consumed power is bigger; The current transformer of this device adopts the cut-off region and the saturation region signal of correction type square wave or pulse-width modulation type PWM square wave to promote, and direct current is become interchange, can promote to surpass the power that the power several times of power transistor (or other power devices) own arrive tens of times.
This high voltage direct current is changed low-voltage direct and supply circuit 16 can provide+3V～+ 6V ,+mV ,+direct voltages such as nV; From the circuit devcie that the generation of ac power frequency clock signal and phase-splitting, phase lock circuitry 41 are connected, all belong to the converter circuit of this device.Waveform after 42 shapings of branch phase clock shaping circuit can be: correction type square wave or PWM PWM-type waveform.
This device is protected at heavy duty machine open/close; the shutdown protective circuit 13 that is connected, start delay protection circuit 15; the technical square-wave signal that all allows when machine open/close " passes through linear zone " fast; power consumption a little only is unlikely the keying of outside heavy load energy moment and concentrates on the power transistor.
Self-supporting dc power supply circuit 19 is to be made of a diode and resistance parallel connection, one end is connected to high voltage direct current conversion low-voltage direct and one group of low-tension supply output of supply circuit 16 and the charging capacitor Cm of a cross-over connection, the other end is connected to and manually boots/shutdown circuit 14 between the emitter of transistor T and the integrated regulator IC3 that high voltage direct current is changed low-voltage direct and supply circuit 16 (being a point place); And high-tension battery group 20 is through the circuit of high voltage direct current conversion low-voltage direct and supply circuit 16, must be earlier by manually boot/shutdown circuit 14 provides starting resistor---low pressure, just can change and supply some groups of low-voltage dc power supplies, obtain+3V～+ 6V, + mV, direct voltages such as+nV; When the voltage of self-supporting dc power supply circuit 19 produces, block this to manually boot/transistor T 1 in the shutdown circuit 14, make it to open circuit, block the high voltage source of high-tension battery group 20, this moment, the voltage stabilizing input voltage of high voltage direct current conversion low-voltage direct and supply circuit 16 was directly continued to provide by the voltage of self-supporting dc power supply circuit 19; And converter circuit is not when working, still keep a direct voltage+mV ,+nV, during incoming call, manually boot/transistor T 1 conducting in the shutdown circuit 14, its emitter voltage recharges this charging capacitor Cm through self-supporting dc power supply circuit 19, keep direct voltage+mV when being full of, this voltage obtains one+nV direct voltage through the transistor T n of voltage stabilizing circuit, to keep two power supplys that high-frequency pulse transformer T4, T5 are required in the supply drive circuit.
And, + nV power supply can speed the time that AC relay CR1 outage is switched, the time that converter circuit starts, because of signal enabling speed fast, the high-tension coil T3 winding of high voltage direct current conversion low-voltage direct and supply circuit 16 is many, the rectification charging time is long, it is slower that high voltage direct current becomes the power supply speed of low-voltage direct, influence output drives, so when civil power is arranged (during standby), reserve one+nV voltage earlier, supply one in good time when treating the civil power outage, two weeks (cycle) power supply, thereafter again by this high voltage direct current conversion low-voltage direct and supply circuit 16 through self-supporting dc power supply circuit service voltage.
The too high or too low testing circuit 11 of this alternating current input power supplying, when civil power cuts off the power supply, outage automatic switchover AC relay CRI opens circuit, this direct current relay CR3-6 contact is opened, send a signal simultaneously to automatic startup/shutdown circuit 12, transistor T J conducting makes integrated circuit (IC) 4 acquisition+4V direct voltages supply with oscillation power, makes converter circuit begin action.
When converter circuit moves: high voltage direct current conversion low-voltage direct and supply circuit 16+the mV direct voltage, supply with a point voltage of integrated circuit (IC) 3 through the diode of self-supporting dc power supply circuit 19, block this to manually boot/machine circuit 14 in the electric current of transistor T 1, realize reducing the purpose that circuit power consumes.
