Abstract:
A circuit arrangement for supplying a load, provided with a DC--DC converter comprising:input terminals for connection to a DC voltage source;a circuit portion comprising inductive means and first capacitive means, said circuit portion interconnecting the input terminals;a switching element for shunting the first capacitive means;a control circuit coupled to the switching element for rendering the switching element conducting and non-conducting with high frequency;a transformer comprising a primary winding and a secondary winding, said primary winding being included in the circuit portion; andan output circuit coupled to the secondary winding, said output circuit comprising:output terminals for connection to the load;rectifying means coupled between the secondary winding and the output terminals; andsecond capacitive means connected between the secondary winding and the output terminals,characterized in that the rectifying means is full-wave rectifying means for ensuring that energy is transferred to the output terminals during two time intervals in each high frequency cycle of an output signal on the secondary winding.
