Variable power supply

This is a small portable ac and dc power supply intended for circuit breaker charging motors and other general purpose applications it will provide ac and dc voltage in three nominal ranges from 0 to 120, 240, and 480 volts, at 1 kva. This power supply has no filter capacitors, and is intended to be operated with no load capacitance if a capacitive load is applied, the output voltage may increase to as much as 140% of the unfiltered output value, and the voltmeter will not read correctly. A variable dc power supply is very important for electronics projects, prototyping and hobbyists for smaller voltages, we normally use batteries as a reliable source instead of using batteries, which have a limited lifetime, a variable dc power supply can be used which is implemented in this.
