Power Supplies 1.0 Power Supply Basics Parts of a Power Supply A DC Power Supply Unit (commonly called a PSU) deriving power from the AC mains (line) supply performs a number of tasks: • 1. It changes (in most cases reduces) the level of supply to a value suitable for driving the load circuit. • 2. It produces a DC supply from a pure AC wave.
Power capacitors within distribution systems provide reactive power to equalize inductive loading from motors, lighting loads, and arc furnaces. If the power capacitor is
Circuit diagram of a capacitive power supply: The vector diagram makes it clear: The majority of the input voltage drops out at the reactance of the capacitor with virtually no power dissipation being created in the capacitor. As the capacitor is directly connected to the power supply, very high demands are made on its reliability.
Full-wave bridge rectifier circuit. Voltage regulator circuit. Power indicator circuit. A capacitive power supply has a voltage dropping capacitor (C1), this is the main component in the circuit. It is used to drop the mains voltage to lower voltage. The dropping capacitor is non-polarized so, it can be connected to any side in the circuit.

This type of power supply uses the capacitive reactance of a capacitor to reduce the mains voltage to a lower voltage to power the electronics circuit. The circuit is a combination of a voltage dropping circuit, a full-wave bridge rectifier circuit, a voltage regulator circuit, and a power indicator circuit.
Selection of the voltage dropping capacitor for capacitive power supply, some technical knowledge, and practical experience requires to get the desired voltage and current output. An ordinary capacitor will not do the same job since the mains spikes will make holes in the dielectric, and the capacitor will fail to work.
In contrast to conventional designs, the capacitive power supplies are short-circuit-proof at the output.
