Devices & Circuits Notes

Half Wave Controlled Rectifiers

Controlled rectifiers, or converters, as they are generally called, are broadly classified into full-controlled and half-controlled types.

SCR Ratings

The ratings of a semiconductor device give the values for the various conditions that a manufactu

SCR in Series

The forward blocking capability of SCRs can be increased when the input voltage exceeds the rating of a single SCR by connecting multiple SCRs in series

Fullwave Center Tap Transformer Rectifier

Full-wave rectifier are more commonly used than half-wave rectifier, due to their higher average voltages and currents, higher efficiency, and reduced ripple factor.

Zener diodes

Zener diodes are used to maintain a fixed voltage. They are designed to 'breakdown' in a reliable and non-destructive way so that they

Voltage Multipliers

In voltage multiplier circuit two or more peak rectifiers are cascaded to produce a d.c voltage equal to multiplier of the peak input voltages
