Abstract
Power supply and method in which the primary current to a transformer is switched on and off to maintain the output of the supply at a desired level. When the energizing current is off, an additional current is applied to the transformer to maintain the core at a level of magnetization such that the full hysteresis characteristic of the transformer is utilized during the next half cycle of operation.
