ABSTRACT:
A control circuit for energizing a magnetron of a microwave oven includes only one switching element for controlling the energization of a primary winding of a high voltage transformer connected to the magnetron resulting in the power supply conducted from a power source to the primary winding. The switching element comprises a triac connected to the primary winding or a relay switch for controlling power supply from a power source to the primary winding. The relay switch can be energized by a Large Scale Integrated Circuit which controls the energization of the magnetron in accordance with a program introduced therein through a manual control.
