Most of these power supplies use a transformer to step down the voltage to a more usable level and also to provide some galvanic isolation to the low voltage circuit. But for circuits where weight ...

Understand the basic dc-dc converter and dc-ac inverter circuits. Understand how to implement transformer isolation in a dc-dc converter, including the popular forward and flyback converter topologies ...

power is measured in watts (W) potential difference is measured in volts (V) current is measured in amperes, also referred to as amps (A) A step-down transformer converts 11,500 V into 230 V.
