Abstract
A switched-mode power supply comprises a transformer (2) having a primary winding (4) connected to a first pair of direct voltage terminals (8, 10) via a switching transistor (6) and having a secondary winding (22) which powers a load (24) via a diode (26). The switched-mode power supply further comprises a second switching transistor (34) which, together with the secondary winding (22), the load (24) the diode (26) and a second pair of direct voltage terminals (38, 40) is configured as a forward converter to power the load from a comparatively low direct voltage (12 V d.c.) supply.
