Solar power or electricity from sun light is so abundant that we can afford to waste it or dissipate it in the form heat. This means that we can use large, high power solar panels to charge batteries with lower power without bothering about how much solar energy is being wasted and how much the […]

How to Design Simple LED Driver Circuits
In this article I have explained how to design your own customized, simple LED driver circuits at home. We will learn how to calculate specific LED configurations for applying the LEDs with appropriate LED driver power supplies. In these driver power supplies I have explained two concepts one by using SMPS boards and the other […]
DC to DC Converter Circuits using SG3524 [Buck, Boost Designs]
A DC to DC converter is basically a switch-mode power supply, designed to work either as a boost-converter to step-up a low voltage DC to a higher voltage DC, or as a buck-converter to step-down a higher voltage DC to a lower voltage DC. The switched mode conversion ensures that the power transfer in the […]
The Role of Inductor Coil in SMPS
The most crucial element of a switched mode converter or an SMPS is the inductor. Energy is stored in the form of a magnetic field in the core material of the inductor during the brief ON period (ton) switched through the connected switching element such as MOSFET or a BJT. How the Inductor Works in […]
110 V to 310 V Converter Circuit
The discussed circuit is a solid state AC to DC voltage converter that will convert any AC input between 85 V and 250 V into a constant 310 V DC output. This kind of circuits are normally use in LCD TV sets for operating the system through inputs from 100 V AC to 250 AC. […]
