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. […]
Simple Mobile Phone Detector Circuit [Tested]
A cellphone or mobile phone detector is actually a high gain op amp amplifier which detects slightest of RF disturbance from a mobile phone, and illuminates an LED. Mobile phones today being the major generator of RF interference is easily picked up by this circuit and can be seen through an LED illumination at the […]
Wireless Mobile Phone Charger Circuit
A wireless mobile phone battery charger is a device that charges a compatible cellphone or mobile phone placed close to it, through high frequency wireless current transfer, without any physical contact. In this post I have explained how to build a wireless cellphone battery charger circuit for facilitating a cordless cellphone charging without employing a […]

The present article explains through a practical example the process of applying the various formulas for making an inverter transformer.The various formulas required […]
How to Convert an Inverter to an UPS
An inverter is an equipment which will convert a battery voltage or any DC (normally a high current) into a higher mains equivalent voltage (120V, or 220V), however unlike an UPS inverters may lack one feature, that is these may not be able to switch from mains battery charging mode to inverter mode and vice […]
