In this post I have explained how the internal body diodes of MOSFETs could be exploited for enabling the charging of battery through the same transformer which is being used as the inverter transformer. In this article we will investigate a full bridge inverter concept and learn how the in-built diodes of its 4 MOSFETs […]

Solar Charge Controller for 100 Ah Battery
This comprehensive solar charge controller is designed to effectively charge a big 12 V 100 Ah battery with utmost efficiency. The solar charger is practically foolproof in terms of battery over charge, load short circuit, or over current conditions. By Vismit Singh The key elements of this 100 Ah solar regulator circuit are, obviously the […]
Calculating Capacitor Charge/Discharge Time using RC Constant
Capacitor charge and discharge periods is usually calculated through an RC constant called tau, expressed as the product of R and C, where C is the capacitance and R is the resistance parameter that may be in series or parallel with the capacitor C. It may be expressed as shown below: τ = R C […]
Battery Full Charge Indicator Circuit using Two Transistors
This little circuit will alert the user regarding a battery reaching its full-charge level (over charge) while it’s being charged, by illuminating an LED. The circuit uses just a couple of transistors as the main active components. Main Feature The main feature of this design is not only its mini design but also its supply […]
Using Treadmill Exercise Bike to Charge Batteries
In this post I have explained how to use an exercise bike or a treadmill for charging a battery through a simple shunt regulator circuit with full charge cut-off feature. The idea was proposed by Mr. Peter Jaffe. Exercise Bike for Charging Battery I have been following your circuit tips for a little while. Very […]
