Low Battery and Overload Protection Circuit for Inverters
A very simple low battery cut-off and overload protection circuit has been explained here. The figure shows a very simple circuit set up which performs the function of an overload sensor and also as an under voltage detector. In both the cases the circuit trips the relay for protecting the output under the above conditions. […]
Make This 1KVA (1000 watts) Pure Sine Wave Inverter Circuit
A relatively simple 1000 watt pure sine wave inverter circuit is explained here using a signal amplifier and a power transformer. As can be seen in the first diagram below, the configuration is a simple mosfet based designed for amplifying current at +/-60 volts such that the connected transformer corresponds to generate the required 1kva […]
Transformerless UPS Circuit for Computers (CPU)
In this post I have explained how to build a simple UPS circuit for backing up computers or PCs during sudden power failures or brownouts. Introduction Normally when we talk about uninterruptible power supplies (UPS) we imagine large inverter units with complex features, where it imperatively needs to be a pure sine wave type. Such […]
Make this Voltage Stabilizer Circuit for Your Car
In this post I have explained about a car voltage stabilizer circuit which could be made and installed in all cars for ensuring a perfectly controlled and stabilized supply for the associated sensitive electronics and gadgets. Understanding Car Electrical A car electrical is probably more volatile than our house electrical, simply because it is generated […]
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 […]
