Diodes Tube Feeding

Dictionary of Electronic and Engineering Terms 'Dih'

Diode ORing is normally used when two different power supplies are connected in parallel and separated by diodes so that if one supply fails the other begins to supply power to the circuit. The diodes stop one supply from feeding current into the other supply while still allowing current from either supply to feed the circuits being powered.

Voltage Multipliers (Doublers, Triplers, Quadruplers, and .

A voltage multiplier is a specialized rectifier circuit producing an output which is theoretically an integer times the AC peak input, for example, 2, 3, or 4 times the AC peak input. Thus, it is possible to get 200 VDC from a 100 V peak AC source using a doubler, 400 VDC from a quadrupler. Any load .
