DC VOLTAGE CHANGER (DESIGN VERSIONS) Russian patent published in 1998 - IPC

FIELD: electrical engineering; power supplies for radio electronic equipment; no-break power supplies. SUBSTANCE: newly introduced in voltage changer are multivibrators. First regulator is provided with one multivibrator built around switching transistors and second one, with two multivibrators using switching transistors which makes it possible to insert by means of transistor switches and distributing transistor switches two additional power transistors into first device and six ones into second device. So, power dissipation takes place across four power transistors in first regulator and across eight ones in second device. EFFECT: reduced temperature of each device and, hence, improved operating reliability. 2 cl, 5 dwg
