## Zener Voltage Pass Regulator Explained with Example

A Zener Diode is a special purpose diode used for voltage regulation in reverse bias. Zener diode work under breakdown region for typical operation. A minimum current of Zener knee current must be maintained to keep the voltage regulated.

## Diode Voltage Doubler Circuit with Tripler and Quadrupler Explained

Voltage Multipliers are electric circuits to increase the voltage by a factor of two, three or four in case of Voltage Doubler, Tripler or Quarple respectively. The Voltage multiplier circuit uses capacitors and resistors to enhance the voltage level.

## Full Wave Bridge Rectifier with Capacitor Filter Design Calculation and Formula

The Bridge type full wave rectifier can convert an AC to DC by the mean of four diodes in such configuration that the output peak voltage remains equal to secondary of transformer peak. In each half cycle, a set of two diodes conduct and block the current alternately.

## Half wave Rectifier with a Capacitor Filter and Ripple Factor Calculation

Rectifiers are the circuit which converts AC Voltage to DC voltage. The half wave rectifier is the simplest type of rectifier with a single diode. The output of the rectifier is filtered with a capacitor filter to smoothen.

## Forward Bias Diode and Reverse Bias Diode Characteristic Graph

A diode can be connected in forward and reverse bias with a source. In Forward bias connection, a diode conducts current like a closed switch. Where in reverse bias, a diode blocks current like an open switch.
