The DC-DC converter, for producing several stabilised DC voltages from a single DC source, has a pulsed input transistor supply the primaries of two transformers via a half wave rectifier. Each primary is connected in series with a pulsed transistor switch. Each transformer has two (or more) ...
2. A pn diode in which a fraction of the injected minority carriers recombine by means of radiative transistors. When the junction is forward biased, electrons from the n region are injected into the p region, where they recombine with ex...
Thus this p-n junction forms the simplest solid-state device, known as a diode. Diodes. Diodes are essentially one-way valves for electronic conductivity. Such a device is very important in a power supply that converts AC to DC current, necessary for many electronic devices. Connecting a ...
Change in the optocoupler diode current results in a change of current into the control pin of IC U1. Variation of this current results in variation of duty cycle and hence the output voltage of the power supply. 4.3 Output Rectification Output rectification for the 5 V output is provided by...
The simplest converter is a full-wave diode bridge, which converts the incoming AC to a fixed DC voltage. This isn't useful in a DC drive, but works fine for AC variable frequency drive (VFD). Standard industrial drives - both AC and DC - use six rectifier devices to form a three-...
