Current supply e.g. adapter, switch actuator or switching network part, with high adjuster, resonance converter and control unit, in which high adjuster is coupled to resonance converter

摘要

Current supply adapter comprises high adjuster (102), coupled to resonance converter (103), and primary control unit (104) coupled both to high adjuster and rseonance converter. Preferably, low adjuster (101) has its output connected to high adjuster, while primary control unit is connected to it.Typically, low and high adjusters, resonance converter and primary control unit are located at primary side of transformer etc. Resonance converter may be coupled to primary of transformer. Control unit may be used for energising active components on transformer primary.
