摘　　要：针对常规晶闸管并联谐振中频电源存在的在熔炼期内输出功率达不到额定功率的问题,设计了一种对 DC/AC 逆变器采用调节功率角φ的触发控制电路,配合原有的 AC/DC 相控双闭环控制电路,可以使中频熔炼电源实现高效控制。To solve the problem that the power-output of thyristor parallel resonant intermediate-frequency power supply is lower than normal rated power, a new trigger control circuit witb adjustment of power factor anale φ for DC/AC inverter is proposed. It makes intermediate-frequency power supply achieve control with high efficiency, cooperating with AC/DC double closed loop control circuit.
