Abstract

PURPOSE:To improve reliability and reduce cost by making it possible to perform digital control based on a count number set by an output setting means. CONSTITUTION:On-time control of a switching element 10 is performed based on a count number set by an output setting means 117 to set the output of a high frequency heating device by increasing the count number when outputs from a voltage detecting means 104 and a current detecting means 105 are under a standard value respectively and reducing the count number when either output value is over the standard value. In the meanwhile, voltage generated at a step-up transformer 101 is controlled to be less than a predetermined value. This makes it possible to reduce the withstand voltage of the switching element 10 and the step-up transformer 101, thereby cost can be reduced.
