Title: Improved generator automatic voltage regulator power supply stages
Inventor: ALISTAIR MACFARLANE
IPC: H02P9/30
Filed: 2019-01-20
Abstract: An Automatic Voltage Regulator (AVR) for a generator uses a cascode connection Xc of a high voltage, depletion mode JFET or MOSFET and a low voltage, enhancement mode MOSFET, as the main control device. The cascoded connected pair of devices is controlled by comparators Comp1, Comp2 requiring a single positive internal supply. Comparator Comp1 senses when the AC line voltage has dropped to zero by resistor Rs connected to line voltage L, and its output switches to low, pulling its output capacitor to zero volts. Clamp diodes Dc prevent an over voltage being applied to the Comp1 input. The internal supply voltage Vsup is provided by a charge pump/voltage doubler comprising capacitor Ccp and Schottky diodes D3, D4, with storage capacitor Cst to store the Dc value of the doubled AC voltage. The power stage may be half wave (fig. 3a) or full wave (fig. 3b). The generator may be a brushless or slip-ring type.
