ups circuit diagram
Hello
Everybody!
I m a new member. My name is Aamir and I m 28. I have my own service centre where i repair computers and other electronic items. I also manufacture UPS, STABILIZERS, UNDER/OVERVOLTAGE AND OVERLOAD protectors on demand. I have made various types of UPS from simple to complicated having power upto 2,000 WATTS but the problem is that they r all square wave while i need a true sine wave ups using simple circuitry and available parts. I have been working on SINE WAVE UPS for 2 years and almost succeeded but the main problem is that POWER TRANSISTORS get so hot on 200W load which means BIG HEAT SINK+COOLING FAN. If u have a good schematic or know about some site please tell me. I'll b very thankful.
