Abstract

Disclosed is a microwave oven including a magnetron, a power supply part supplying an AC power and a high voltage transformer generating a high voltage with the AC power from the power supply part, comprising a power controller part interrupting the power supply to the magnetron where it is determined that the voltage of the power supplied from the power supply part is lower than a predetermined allowable lower limit voltage. With this configuration, application of the voltage lower than the allowable lower limit voltage can be prevented, and in addition, the stability of the circuit can be enhanced.
