ABSTRACT:
A single-ended transformer drive circuit includes a transformer having a primary winding and a secondary winding and a switching transistor connected to the primary winding of the transformer and adapted to turn on and drive the transformer in the forward direction along its hysteresis curve, whereby an output voltage is generated in the secondary circuit of the transformer. An auxiliary transistor circuit is coupled to the transformer for driving it in the reverse direction along its hysteresis curve when the switching transistor turns off, whereby the transformer is reset and prepared for the next cycle of operation when the switching transistor turns on again.
