| Abstract: | Aiming at the difficulty to start,this paper provides a new control circuit for thyristor medium frequency power supply.The circuit softly starts the power supply in the way of sweeping-frequency and zero-voltage,and the inverter trigger circuit of it is made up with phase-locked loop.The experimental results show that the new control circuit is simple and efficiency.The ratio of successful start is very high. |
