Simple Voltage Multiplier Circuits Explored
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 […]
6 Useful Voltage Controlled Oscillator Circuit Explored
In this post I have explained how to build 6 useful voltage controlled oscillator circuits, using various op amps and integrated circuits. As the name suggests, a voltage controlled oscillator or a VCO circuit is an oscillator circuit whose output frequency can be controlled or varied through an adjustable control voltage input. This means, if […]
MPPT vs Solar Tracker – Differences Explored
The post investigates two popular solar harnessing counterparts the MPPT and the solar tracker, and figures out the major differences between these two outstanding free energy spinning devices. It’s true that our planet is blessed with many free energy sources such as wind energy, hydro energy, sun or solar energy etc but unless these are […]
