ABSTRACT:
A power supply for a magnetron comprises an inverter circuit for converting a direct voltage obtained from a commercial frequency power source into an alternating voltage of a higher frequency by switching a switching element, a transformer with its primary winding connected to the inverter circuit, a voltage doubler with its input connected to a secondary winding of the transformer and with its output connected between a filament and an anode of a magnetron, and a resonant circuit formed in the voltage doubler for smoothing a current through the magnetron.
