Abstract
The invention relates to a circuit for a microwave cooker, whereby a DC power supply is provided to supply the same and a DC voltage battery and auxiliary devices such as safety equipment, lamps, display devices, timers and voltage controllers for the magnetron as well as the magnetron itself, whereby a DC/DC converter is provided to supply the high voltage for the magnetron which basically consists of a transistor circuit, a control device and a high-frequency transformer with a downstream diode rectifier, and operates at a frequency of over 1 kHz
