4 Simple Battery Desulfator Circuits Explored
In this article we investigate 4 simple yet powerful battery desulfator circuits, which can be used to effectively remove and prevent desulfation in lead acid batteries. The first method uses PWM pulses from a 555 PWM circuit, the second method implements an ordinary bridge rectifier for implementing a 100 Hz frequency based desulfation, the 3rd […]
Lead Acid Battery Charger Circuits
The lead acid battery charger circuits I have explained in this article can be used for charging all types of lead acid batteries at a specified rate. This article explains a few lead acid battery charger circuits with automatic over charge, and low discharge cut off. All these designs are thoroughly tested and can be […]
Simple Frequency Meter Circuits – Analogue Designs
The following simple analogue frequency meter circuits can be used for measuring frequencies which may be either sine wave or square wave. The input frequency which is to be measured must be at least 25 mV RMS, for optimal detection and measurement. The design facilitates a relatively wide range of frequency measurement, right from 10 […]
Motorcycle Voltage Regulator Circuits
In the article below I have explained a compilation of simple yet accurate motorcycle voltage regulator circuits, which can be used for regulating the varying alternator voltage into a fixed DC voltage. Voltage regulator circuit is very important in motorcycles and two wheelers since they ensure a regulated battery charging thus keeping the battery safe […]
5 Useful Motor Dry Run Protector Circuits Explained
The 5 simple dry run protector circuits presented here shows simple methods by which insufficient water conditions inside an underground tank can be sensed without introducing probes inside the underground tank, and thus preventing any possibility of motor dry running. The circuit also incorporates an overhead water overflow control feature. The idea was requested by […]
