In the utility model, the circuit of the main control board 2 includes six parts, the main control board 2 includes a single-chip module circuit 21, a control signal acquisition module circuit 22, a synchronization signal acquisition module circuit 23, a drive module circuit 24, a thyristor output module circuit 25 and a voltage and current feedback module acquisition circuit 26, the control signal acquisition module circuit 22, the synchronization signal acquisition module circuit 23, and the drive module circuit 24 are respectively electrically connected to the single-chip module circuit 21, and the two ends of the voltage and current feedback module acquisition circuit 26 are respectively electrically connected to the thyristor output module circuit 25 and the single-chip module circuit 21. The single-chip module circuit 21 adopts a high-performance 32 single-chip control circuit, and the synchronous signal acquisition module circuit 23 adopts a synchronous signal circuit with electrical isolation. In the embodiment of the utility model, the synchronous signal acquisition module circuit 23 has a high voltage isolation capability of 5kV, and can detect 10V~265V and correctly output the power grid synchronization signal. The synchronous signal acquisition module circuit 23 can use a mutual inductor to achieve electrical isolation. The control signal acquisition module circuit 22 is used to connect with other control signal output devices. The voltage and current feedback module acquisition circuit 26 uses a mutual inductor with electrical isolation effect as a voltage and current sampling device. The mutual inductor is made of amorphous magnetic core and has the characteristics of high magnetic saturation intensity, low coercive force and low loss. The mutual inductor made of this material has the characteristics of high precision and accurate measurement range. The current and voltage sampling part adopts a sampling method based on the midpoint of the voltage reference, that is, the signal voltage is superimposed on the AC signal on 0.5 times the voltage reference. The advantage of using this method is that it reduces the conventional diode rectification method, has the characteristics of low voltage generated by the mutual inductor, and small sampling resistance. The electrically isolated drive module circuit 24 part. First, the isolated synchronous signal sampling circuit provides the single-chip microcomputer with an accurate synchronous signal waveform. The single-chip microcomputer analyzes the synchronous signal waveform internally and waits for the arrival of the control signal. When the single-chip microcomputer receives the control signal, the single-chip microcomputer outputs the driving waveform to the isolated driving circuit. At this time, the driving thyristor starts to output. The output voltage is determined by the control signal. The isolated voltage and current sampling circuits work synchronously and feed back the real-time voltage and current signals to the single-chip microcomputer. The single-chip microcomputer adjusts the thyristor output voltage, current, and power according to the feedback signal, thereby forming a closed-loop system. In addition, the single-chip microcomputer also judges whether there will be overvoltage or overcurrent based on the feedback signal, and makes relevant protection in time, cuts off the output of the driving circuit, and disconnects the thyristor output.With the support of the unique algorithm of the single chip program, the output voltage is stable, accurate and highly linear. The utility model is provided with two outputs, which reduces customer costs and saves assembly space.
