ABSTRACT:
A switched mode power converter is provided which includes a transformer (2) having a primary winding (2a) and at least one secondary winding (2b); a primary side active switch device (S1) coupled to the primary winding for selectively applying an input voltage to the primary winding; and a secondary side rectifier circuit including an output filter (6, 12) coupled to the at least one secondary winding (2), and first and second active switch devices (16, 14) coupled between the at least one secondary winding (2b) and the output filter. The switch devices are arranged such that each one is operable independently of the other to block current between the at least one secondary winding and the output filter in an opposite direction to the other. This facilitates better regulation of the converter and avoids the occurrence of voltage spikes encountered in existing configurations.
