Abstract

The primary side of a DC-to-DC converter produces alternating positive and negative pulses separated by quiescent periods, coupled through a transformer TX to the secondary side, which comprises a bridge circuit of two MOSFET transistor switches Q1, Q2 and two inductors L1, L2 with the secondary winding STX connected between the two transistor-inductor junctions, the switches being controlled from the transformer. Each of the switches Q1,Q2 is controlled from separate control winding means DX1, DX2 on the transformer via a diode D1, D2 and a control transistor Q3, Q4. Alternatively, a single control winding and further diode coupling circuitry may be used.
