Electrical power supply circuit, in particular for a wave generator for a pulse radar

Claim 1

An electrical power supply circuit for a pulse radar wave generator, comprising: a pair of DC input terminals for connecting to a direct current low voltage source; a controlling input for receiving a control signal at the repetition frequency of radar pulses or at a multiple of said frequency; a plurality of high voltage high power DC terminals for connecting to respective electrodes of said pulse radar wave generator; a common transformer core; a first plurality of primary windings, wound on said common transformer core, and arranged in series with a corresponding first plurality of electronic power high frequency switches having respective control electrodes connected to said controlling input; at least a second plurality of primary windings, wound on said transformer core, and arranged in series with a corresponding second plurality of electronic power high frequency switches having respective control electrodes connected to said controlling input, each of said plurality of primary windings being respectively connected across a capacitor, the respective capacitors being connected in series across said pair of DC input terminals; a plurality of second windings wound on said transformer core, each of said plurality of secondary windings being connected across a corresponding first rectifier mounted in series with a corresponding capacitor and connected to be conductive when a corresponding electronic power high frequency switch is blocked; wherein all corresponding capacitors of said plurality of secondary windings are connected in series and define said plurality of high voltage high power DC terminals.
