DIRECT-TO-DIRECT VOLTAGE CONVERTER Russian patent published in 1997 - IPC

FIELD: electric engineering. SUBSTANCE: device has power supply, which positive terminal is connected to emitter of transistor, transformer, which has two primary windings and one output winding. Collector of transistor is connected to terminal of primary winding, which another terminal is connected to negative terminal of power supply which is also connected through resistor to terminal of second primary winding and emitter of transistor which base is connected to another terminal of this winding. Terminal of output winding of transformer is connected in series to rectifying diode. Smoothing capacitor is connected in parallel to output terminals of rectifying diode. Base circuit of transistor has resistor and RC-circuit which is parallel to it and comprises capacitor and resistor. Second capacitor is connected to emitter circuit. Second terminal of capacitor is connected to first terminal of second primary winding of transformer. EFFECT: increased functional capabilities. 2 dwg
