ELECTRONIC VOLTAGE REGULATOR Russian patent published in 1999 - IPC

FIELD: automatic- control equipment for space engineering and national economy. SUBSTANCE: electronic device incorporating parametric voltage regulator built up of series-connected voltage regulator diode and resistor, resistive divider, input amplifier, output transistor whose collector is connected to generator field winding has its input amplifier made in the form of transistor optocoupler built around light-emitting diode and transistor; positive terminal of optocoupler light-emitting diode is connected to center tap of parametric voltage regulator and its negative terminal, to center tap of resistive divider; output transistor base is connected to emitter of optocoupler transistor and through resistor, to negative terminal of power supply; output transistor collector is connected through feedback resistor to same positive terminal of optocoupler light-emitting diode. Desired regulation accuracy within (1 + 2%) is ensured in temperature range of plus 40 to minus 40 C. EFFECT: improved regulation accuracy. 2 dwg
