Here is a 100 Watt inverter circuit using minimum number of components. I think it is quite difficult to make a decent one like this with further less components. Here we use CD 4047 IC from Texas ...

Here is a simple but inexpensive inverter for using a small soldering iron (25W, 35W, etc) In the absence of mains supply. It uses eight transistors and a few resistors and capacitors. Transistors Q1 ...

Recent developments in IGBT and FWD (free wheeling diode) devices are enabling designers to achieve higher switching performance, lower electrical losses, and higher temperature operation in high ...

Walton has announced a five-year warranty facility for the PCB (Printed Circuit Board) of some locally manufactured air conditioner (AC) models. In addition, customers are entitled to a 10-year ...
