Abstract
A method for controlling magnetrons with regard to their microwave power in those cases where a multiple of magnetrons are present. The method includes connecting two or more magnetrons in parallel with a power unit operative in generating a high voltage for operating the magnetron is connected to respective magnetrons and includes a current measuring circuit by which the anode current passing through respective magnetrons is measured on the high-voltage side of the magnetrons. The current measuring circuit is galvanically separated from a control circuit, which is arranged to control the anode current of a respective magnetron in response to a signal received from the current measuring circuit. Also an arrangement for carrying out the method.
