Abstract

The present invention relates to a method and a device for providing power to a magnetron from an alternating voltage source. According to the invention, the power supply is accomplished by said alternating voltage being rectified into a rectified voltage which is then converted into a high direct current for powering said magnetron, wherein the power provided to said conversion is controlled based upon a detected actual effect in the power supply means.
