Understanding the concept of power in AC circuits is essential for anyone working with electrical systems or studying the subject.

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

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

Rectification is the process of converting alternating current or voltage into direct current or voltage.

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.

The transistor is used to amplify the weak signal a CE amplifier connection is shown in below figure.

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

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
