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 ...

PCB，即印制电路板（Printed Circuit Board），是现代电子设备中不可或缺的重要部件。它是电子元器件电气连接的提供者，是电子产品的大脑和心脏，被广泛应用于各种电子设备中。 那么，PCB板究竟是什么意思？它的工作原理和应用场景是什么？本文一一道来。

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 ...
