Abstract

A very high voltage stabilized power supply device for a pulse radar system, in particular an airborn radar, which comprises a primary winding connected in a series with an electronic power commutation switch actuated at the recurrence frequency of the pulses produced by the radar, or at a multiple frequency of the recurrence frequency, to the terminals of a rectified and filtered voltage supply source. The primary is wound around an inductive element on which are wound a plurality of secondary windings with a primary-secondary winding transformation ratio equal to unity. Each secondary winding is connected in series to a diode with a filter capacitor in parallel. The outputs of the secondary circuits are connected in series so that their voltages accumulate at the output of the power supply unit. Several modules of this type may be used, with their commutating elements actuated on a staggered basis.
