ABSTRACT:
In a multiresonant DC--DC converter provided with a switching element (S1), a transformer (T) and a rectifier coupled to the secondary winding (S) of the transformer, the rectifier is constructed as a diode bridge (D1, D2, D3, D4). It is achieved thereby that the maximum amplitude of the voltage across the switching element is comparatively low. The switching element is highly suitable for supplying a network of LEDs.
