ABSTRACT:
An inverter power control circuit for a high-frequency heating apparatus of a half-bridge type which comprises an inverter. The inverter power control circuit comprises a first current transformer for detecting a current flowing through a first free-wheeling diode in the inverter, a second current transformer for detecting a current flowing through a second free-wheeling diode in the inverter, a pulse supply circuit for supplying a pulse to drive the circuit at an initial state, an ON time control signal generator for generating an ON time control signal to control ON times of first and second switching devices in the inverter, a first drive controller for outputting a first drive control signal in response to the current detected by the first current transformer, the pulse from the pulse supply circuit and the ON time control signal from the ON time control signal generator to control the ON time of the first switching device in the inverter to control the power of the inverter, and a second drive controller for outputting a second drive control signal in response to the current detected by the second current transformer and the ON time control signal from the ON time control signal generator to control the ON time of the second switching device in the inverter to control the power of the inverter.
