The circuit was designed to build a stable power supply the will provide a regulated voltage from 40 V to 70 V in a 3 A current. 2N3055 – a complementary Silicon Epitaxial-Base planar NPN transistor ...

Building a regulated power supply is one of the best start-up projects for beginners. Besides, it can also be used for other future projects as well. A power supply is always an add-on for an ...

The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.

Fig 1. This efficient pre-regulator for a dc power supply uses an optical feedback loop to minimize dissipation rather than the traditional optically isolated TRIAC drivers. Fig 2. The PSpice ...
