Abstract

A magnetron (M) serving as microwave source in a microwave oven is driven by a Switch Mode Power Supply (SMPS). The resonance circuit of the Power Supply contains a transformer (Tr), the secondary side of which is connected to the magnetron (M) via a voltage multiplier in the shape of a rectifier and voltage doubler circuit (C3, C4, D3, D4). In order to obtain a feed-back signal, which is a measure of the power fed to the magnetron in order to enable regulation of this power, a current transformer (ST) is connected in series with one of the diodes (D3) in the rectifier and voltage doubler circuit. The output signal of the current transformer (ST) is compared with a reference signal and the result of the comparison is used to control the switch frequency and thereby the power.
