FIELD: power supplies for resistive or inductive loads. SUBSTANCE: converter has transistor connected in series between negative electrode of voltage supply and first lead of inductor; pulse generator circuit; first capacitor and rectifier diode inserted, respectively, in first and second parallel circuits between emitter and collector electrodes of transistor; second capacitor connected in parallel with voltage supply to produce ripple capacitance for voltage supply. Transformer, inductor, and capacitors form resonator that operates in series and in parallel with transistor. EFFECT: improved efficiency of converter. 10 cl, 6 dwg
