EXTREME POWER REGULATOR Russian patent published in 1998 - IPC

FIELD: autonomous power supply systems with non-regulated primary direct current power supply. SUBSTANCE: device has unit of power gates and serial circuit of with its inner resistor, choke winding, reverse diode unit and load. In addition device has positive feedback circuit, which has serial circuit of two resistors and is connected between common line and terminal which is shared by choke winding, unit of power gates and reverse diode unit. In addition device has amplifying transistor and transistor which works as non-linear resistor. Collectors of these resistors are connected to control input of unit of power gates; their bases are connected to common terminal of resistors which serves as output of positive feedback circuit. Emitter of amplifying transistor is connected to output resistor of power supply. Emitter of transistor which works as non-linear resistor is connected to common line. EFFECT: simplified design, improved power characteristics. 2 dwg
