METHOD OF CAPACITIVE ENERGY RECUPERATION AND DEVICES FOR ITS IMPLEMENTATION (VERSIONS) Russian patent published in 2008 - IPC H03K3/53 H03K17/04 H02M3/335 

FIELD: physics.

SUBSTANCE: group of inventions may be used in impulse devices operating in the quasi-resonant or resonant mode, including voltage converters, pulse generators with or without magnetic compression. For the elimination of the emergency power oscillation mode and to increase their efficiency, a capacitive energy recuperation method is proposed involving the following: the recuperated capacitance is connected to the primary winding of the recuperation link pulse transformer, which is used to transform its voltage, and the recuperated energy is transferred to the filter capacitor or another receiver of this energy through a rectifying element. Three devices implementing this capacitive energy recuperation method are proposed: a voltage converter, a unipolar pulse generator, and a pulse generator with magnetic compression. The voltage threshold in the capacitor C1, at which the process of recuperation of its energy into the filter capacitor C0 begins, depends on the recuperation link transformation ratio and is determined using the formula: where: Uc1 is a voltage of the recuperated capacitor C1, Uc0 is a voltage of the filter capacitor, N1 is a number of turns of the recuperation link transformer primary winding, N2 is a number of turns of the recuperation link transformer secondary winding. The energy transfer is carried out in the oscillation mode, with no losses in the switches.

EFFECT: increased reliability and efficiency of resonant and quasi-resonant circuits.
