Power Supply Circuits

The main technical function of the proposed voltage regulator is voltage stabilization. It is capable of stabilizing an input voltage ranging from 0 to 600 Vdc to an output voltage ranging from 100 to 560 Vdc, with a maximum current of 800 mAdc and maximum power dissipation of 100 W. The unit also exhibits good […]

In this article I will try to explain the construction of a 1.23 V to 50 V adjustable switching power supply circuit using the IC LM2576. The LM2576 family of regulators is a monolithic integrated circuit that performs all of the active operations of a step-down (buck) switching regulator. It offers exceptional line and load […]

In this post I have explained some basic facts about DC to DC buck converters and also learn how to build a simple buck converter circuit. A buck converter is also popularly known as a step-down converter, since its basic function is to step down a higher input voltage level to a lower output voltage […]

In this article I have explained how an input AC source could be increased to any desired levels using simple voltage multiplier circuits, built with capacitors and diodes. Thus the basic function of a voltage multiplier circuit is to multiply a given AC voltage source to any higher desired level, simply by adding the relevant […]

Fuel cells have the capacity to be the most effective and ecologically friendly power source ever devised. Since fuel cells are able to generate drinking water as a by-product, they are indeed an appealing replacement for traditional power generation. How much more could you want from a source of energy? History Sir William Grove developed […]

In the following post I have explained two straightforward dummy load circuits: the first one can be used for testing high current power supplies, and the second design can be used for testing large power amplifiers. Suppose you have a 10 amp power supply and you want to confirm the 10 amp output through some […]
