Abstract

A new method that overcomes the disadvantages of the conventional magnetron output power (MOP) control is presented in this paper, The conventional LC single-phase half-wave doubler supply has been modified in order to allow the use of a manually controlled and/or PC-controlled electronic variator. Trains of high-voltage pulses followed by inhibited high-voltage pulses are periodically applied on the magnetron anode yielding a corresponding variation of the average MOP, with programmed steps, maintaining the advantage of peak microwave output power operation. The PC-controlled system provides a practically continuous variation of the magnetron average output power
