Abstract

A high-frequency rectifying apparatus, which rectifies an incoming AC voltage (Un) from a mains supply to an outgoing DC voltage (Uo) at a given level. The apparatus contains primary a power circuit with a rectifier bridge (DB) across its input, and a power transistor (TR) as switching element. In accordance with the invention, the primary power circuit comprises only one magnetically coupled inductor (TF) with two windings (k1 and k2), where the primary winding (k1) is connected in the primary power circuit to the power transistor (TR) and the secondary winding (k2) is connected to a secondary power circuit. The power transistor (TR) is then controlled as that the rectifier works as a so-called fly-back rectifier, i.e. during the interval when the transistor (TR) conducts, magnetic energy is stored by means of the primary current i1 and during the time interval when the transistor (TR) is blocked the inductor (TF) will be discharged across the secondary power circuit. The rectifier apparatus furthermore contains two regulation means R1 and R2 forming a regulation system for converting the rectified input voltage to the desired output direct voltage (Uo).
