ABSTRACT:
A power supply circuit for driving a magnetron equipped in a microwave oven, provides a stable power to the magnetron by preventing instability of output voltage due to LC resonance between a high voltage condenser (HVC) for driving a secondary winding of a transformer and the magnetron, and by good insulation between the secondary windings of the transformer in a switching mode power supply employing pulse width modulation.
