CONVERTER OF UNIPOLAR VOLTAGE INTO BIPOLAR VOLTAGE

摘要

FIELD: electricity.;SUBSTANCE: converter of unipolar voltage into bipolar voltage is related to the field of electric engineering and may be used in sources of secondary power supply of radio electronic equipment. In available circuit of unipolar voltage converter into bipolar voltage, including divider of input voltage from serially connected resistors, operational amplifier (OA), non-inverting inlet of which is connected to medium point of divider, and outlet is connected to bases of transistors of symmetrical emitter repeater (ER), and emitters of transistors of symmetrical emitter repeater, creating outlet of converter, are connected to inverting inlet of operational amplifier, moreover, collectors of n-p-n and p-n-p transistors are connected accordingly to positive and negative poles of input voltage source, and outlet of converter is connected to poles of input voltage source via pair of filtering capacitors, connection is broken between point of transistor emitters connection and output of converter, and new induction is introduced into this break, as well as new resistor connected between point of transistor emitters connection and non-inverting inlet of OA.;EFFECT: higher efficiency factor, reduced heat release, and also reduction of dimensions and weight of converter.;2 dwg
