Abstract

A magnetron generator, especially for high-frequency heating purposes, in which the power circuit of the magnetron generator includes a control circuit of a control device, the output of which control device is connected to an electromagnet coil of the magnetron magnetron system, said control device, in operation, controlling the energizing current through the electromagnet coil to stabilize the DC current in the magnetron, and the power circuit includes a control switch to connect and disconnect the magnetron, characterized in that the magnet system of the magnetron together with the electromagnet coil constructed as a separate control coil, is formed by a permanent magnet, whose magnetic field reinforces that of the electromagnet coil and in which the control device It also comprises an auxiliary control circuit which, when the magnetron is connected by the control switch, it supplies an auxiliary drive current, which decreases with the time delay, for the magnetron electromagnet coil constructed as a control coil.
