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 varia
tion of the average MOP, with programmed steps, maintaining the advantage o
f peak microwave output power operation. The PC-controlled system provides
a practically continuous variation of the magnetron average output power.
