VOLTAGE CHANGER WITH VARIABLE FREQUENCY

摘要

A voltage changer with variable frequency comprises power transistors united by collectors with a primary transformer winding. Two supplementary transistors having emitter-collector junctions in parallel connected to corresponding timing capacitors are also brought in the changer. Collectors of supplementary transistors are connected to base of transformer windings, emitters are connected with a single point of timing capacitors and adjustable resistor. Supplementary winding of the transformer is connected through resistor to bases of supplementary transistors and cathodes of diodes, united anodes of which are connected to emitters of supplementary transistors.
