Energy-changer between power supply and load - uses rectifier or variable-ratio transformer or AC current pulse converter

摘要

The use of an energy-changer between an electrical source and a load can improve the overall efficiency. For example, the energy-changer could convert alternating current into pulses for supplying gas-filled lamps, utilising the afterglow effect of the lamps. For heating apparatus, the energy-changer could be a rectifier, thereby improving the power factor. For controlling the current to a set of street lamps, the energy-changer could entail a variable-ratio transformer, obviating the need for switches. USE/ADVANTAGE - Energy-converter between electrical source and load which can improve overall efficiency.
