FIELD: electric engineering. ^ SUBSTANCE: capacitor and throttle with winding are added to push-pull voltage converter, and the winding with its output from medium point is connected to the first extreme outputs of resistive voltage dividers and to plus of supply source, and by its extreme outputs - to according inputs of primary windings of transformer, between which capacitor is connected. It made it possible to improve reactive resistance of power circuits in push-pull converter, to reduce switching currents and active losses at elements of electric circuit, and also to suppress short-term bursts of currents at capacitor, which cause electromagnet radiations and bring noise into operation of converter. ^ EFFECT: improved reliability, reduced level of switching losses, level of electromagnetic radiations and improvement of energy indices. ^ 1 dwg |
