Abstract :
The approximate analysis of a thyristor frequency converter for induction heating and melting is described. The method for calculating the smoothing reactor inductance, which will provide the continuous mode of inverter input current operation, is proposed. The laboratory prototype of the above converter has been made and examined. The results of the experiments are in good agreement with the theoretical calculations
