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

摘要

An electrical power supply circuit, in particular for a pulse radar wave generator, includes a chopper regulation circuit and a transformer which is fed from a low voltage source. The primary winding of the transformer of the circuit has a plurality of primary windings wound on a common transformer core. Each of the primary windings is connected to the low voltage source via an electronic power switch controlled by a voltage regulation signal at the repetition frequency of the radar pulses or at a multiple of the frequency. The transformer secondary includes a plurality of secondary circuits with their outputs connected in series between the very high voltage output terminals of the power supply circuit as a whole. Each secondary circuit includes a secondary winding wound on the common transformer core and connected in series with a rectifier connected to oppose the voltage induced by the primary current, together with a filter capacitor connected in parallel with the series circuit consituted by each secondary winding and each rectifier.
