摘要： An object of the present invention is to provide an inverter circuit in which soft start can be implemented by a simple circuit added thereto. In high-frequency heating apparatus for driving a magnetron, a DC power supply is chopped by two semiconductor switching devices, and this is output as an AC current through a resonance circuit. The high-frequency heating apparatus includes a dead time generation circuit for turning off the semiconductor switching devices concurrently. In the high-frequency heating apparatus, a drive unit for driving the aforementioned semiconductor switching devices has a function of limiting the lowest frequency of a frequency with which the semiconductor switching devices are driven. The aforementioned lowest frequency is set to be high at the beginning of operation of the high-frequency heating apparatus, and the aforementioned lowest frequency is set to be lower gradually thereafter.

摘要： Since the exposed collector part 32 of one semiconductor switching element 29 is attached to the heat radiating fin 42 by coating and filling a thermal conducting filler therebetween via spacers 33, 34 and 35, and the exposed collector part 37 of another semiconductor switching element 36 is directly attached to the same heat radiating fin 42 by coating the thermal conducting filler 41 thereto without any spacer, heat resulting from switching losses can be effectively transmitted to the heat radiating fin 42 and can be radiated therefrom. To effectively transmit heat, which results from switching losses, to a heat radiating fin and to radiate the same even if two semiconductor switching elements are connected in series, a collector part is exposed on the rear side thereof, and the two semiconductor switching elements are attached to a single heat radiating fin.
