IMPROVED SNUBBER ARRANGEMENTS WITH ENERGY RECOVERY FOR POWER CONVERTERS USING SELF-EXTINGUISHING DEVICES Abstract of the Invention Energy trapped in the snubbers connected to a dc-ac power converter is more efficiently restored to the dc source by means of an energy recovery transformer with a reset circuit branch for improving the reset of the trans- former following a period of energy recovery. The reset circuit branch damps out oscillations between the recovery transformer and the overcharged shunt capacitive snubber end may also be used to dissipate the magnetizing current of the energy recovery transformer.
