ABSTRACT:
There is constructed a constitution such that a shunt resistor30is interposed in series with a portion capable of measuring an output current of a unidirectional power source portion1of a high frequency heating apparatus and a voltage generated at the shunt resistor30is outputted by a buffer31. Further, an operational amplifier3101having a high input impedance is used for the buffer31. Further, a diode bridge101and a semiconductor switching element205are fixed to a common heat radiating plate33, the heat radiating plate33is formed with a notched portion33ato thereby ensure insulating distances to the diode bridge101and the semiconductor switching element205, and the shunt resistor30is arranged on a straight line the same as that between the diode bridge101and the semiconductor switching element205.
