Ac Voltage

Some articles on ac voltage, voltage, ac:

Motor-generator - Variable AC Voltage Power Supply
... Before solid state AC voltage regulation was available or cost effective, motor generator sets were used to provide a variable AC voltage ... The DC voltage to the generators armature would be varied manually or electronically to control the output voltage ...
STATCOM - Uses
... to support electricity networks that have a poor power factor and often poor voltage regulation ... There are however, other uses, the most common use is for voltage stability ... A STATCOM is a voltage source converter (VSC)-based device, with the voltage source behind a reactor ...
IMPATT Diode - Principle of Operation - Impact Ionization
... Let an AC voltage of sufficiently large magnitude be superimposed on the dc bias, such that during the positive cycle of the AC voltage, the diode is driven deep into the avalanche breakdown ... At t=0, the AC voltage is zero, and only a small pre-breakdown current flows through the diode ... As t increases, the voltage goes above the breakdown voltage and secondary electron-hole pairs are produced by impact ionization ...
