An electronic circuit built using four diodes that converts an AC input to a DC output is called a bridge rectifier. We refer to this procedure as a full wave rectification. In […]

This article teaches how to create a basic variable power supply circuit with the use of the 2N3055 transistor and a few additional passive elements. It comes with adjustable variable […]

Applications needing strict voltage controls and ripple rejection standards can utilize the circuit shown below. All leftover ripple factor is fully corrected thanks to the configuration of the transistor pair. […]

Transformers are a common component of traditional power supplies, however they may be large and heavy for low-power uses. A more compact design is provided by transformerless designs. However, the […]

This article transforms a basic capacitive power supply into a safer and more versatile design. The resulting transformerless circuit will offer: This improved design will be suitable for powering a […]

The following transformerless power supply uses an MJE13005 transistor for voltage regulation. It acts like an amplifier controlled by a base zener diode to set the output voltage. A 3uF […]
