The adjustable voltage power supply circuit of the thyristor is shown as above.The circuit output voltage is 50~100V and the current is 3A.The high voltage parts adopt VS1 and VS2 tubes and they are used as crystal phase control.It is corresponding to the output voltage and load change and it controls waveform dutyfactor,and it can improve the linear regulator's transformation efficiency. VT2 and VT3 are current limit circuit,VT1 has current limiting function and C1 is vibration preventing capacitance.The circuit output voltage is 70 V, and its load current is 0 ~ 2 A and its voltage changes within ±3V.
