INVERTER Russian patent published in 1994 - IPC

FIELD: electric energy conversion. SUBSTANCE: inverter has nonsaturating power transformer 1, two transistors and change-over transformer 2 which secondary windings 3, 4 are connected to emitter junctions of transistors. Primary winding 5 of change-over transformer 2 is connected between primary semi-windings 6, 7 of power transformer and to feedback winding of power transformer 1 via low-resistance resistors. Automatically changed delay of unblanking of due transistor and automatic balancing of mode of remagnetization of magnetic core of transformer is realized in inverter. EFFECT: improved operational characteristics of inverter. 1 dwg
