12Vdc to 220Vac inverter

Very simple 50 watt inverter using MJ2955

Today I need to use AC lamp and Soldering iron at outdoor which no 220V AC electrical current. My friend borrow the 150 watt inverter of me, which I used it in car. It does works so well. So I not have any inverter. Therefore I need to build new inverter. Main idea of circuits. […]


Simple working principle of the inverters

The inverter working principle as shown in Figure 1. The main device is a transformer. Which have 12V-0-12V, a common iron core. But instead we use the power input as 220 volts. Then power output as 12 volts. The way the switch differential is power AC input as 12 volts and output to AC 220 […]


Operation of 200 watt inverter diagram

Yesterday, I recommend Simple working principle of the inverters. Which you have understood well. Today we see Operation of 200 watt inverter diagram continuously. In the block diagram of Figure 1. Starting from the frequency generator circuit or the oscillators that works with IC2 numbers SG3526 Which is IC pulse width modulation as figure 2 […]


Inverter 12V to 220V 100W by Transistor

This circuit power Inverter 100W, it easy and good ideas. When use the electric appliances that want 220V AC 50HZ, which have small-sized about 100Watt not exceed. By when you apply outside home, as a result have to have Mini power inverter about 100Watt, perform modify from work electricity forces of battery 12V give tall […]
