Abstract
The electrical power supply to a magnetron (M) is regulated as a function of an instantaneous microwave power setpoint by: predetermining and storing () a value (η) for the electrical efficiency of the magnetron; inputting () a setpoint mean microwave power value, and converting it into a low frequency setpoint instantaneous power signal that is sampled at high frequency; measuring () and sampling the instantaneous values of anode current and of the high voltage fed to the magnetron; calculating () the difference at a sampling instant (n) between the setpoint instantaneous microwave power and the product of the current multiplied by the high voltage multiplied by the efficiency; determining an instantaneous microwave power value at the consecutive sampling instant (n+1) that is corrected as a function of a predetermined regulation relationship that is valid at said instant (n+1); and converting it into an analog signal representative of the corrected instantaneous microwave power for powering the magnetron.
