INVERTER DEVICE FOR MICROWAVE OVEN

摘要

PROBLEM TO BE SOLVED: To provide an inverter device for a microwave oven capable of properly controlling an anode current of a magnetron at lower cost than a conventional inverter device. SOLUTION: A voltage rectified by a rectification circuit 2 in a direct current power supply circuit 31 is divided by voltage dividing resistances 17a and 17b. A control circuit 37 detects changes of a power supply voltage by referring to the divided voltage to change an output condition of an inverter circuit 32 based on its change condition in order to control an anode current of the magnetron 16.
