ABSTRACT:
A circuit suitable for use in an induction range. The circuit includes a resonant inverter having first and second gate controlled thyristor switches, the main conduction paths of which are serially connected between the power supply terminals. Trigger pulses for the switches are derived from the current supplied to the inverter load coil. The pulses are timed to prevent the first switch from being closed before the second switch has opened so that both switches can never be conductive at the same time. It also includes circuitry for stopping inverter operation in the event of an overcurrent condition and circuitry for adjusting the inverter output power.
