This is the inverter circuit which capable to convert 12V DC to 220V AC dan handle about 50 Watts small electronic appliances. With this circuit, you can use a 12V accumulator / lead acid battery to operate some of your electronic appliances which not exceed 50W of total power consumption.

The above inverter circuit converts 12VDC to 220VAC with power of about 50W. To circuit consists of the oscillator around the IC1, a divider IC2, an unstable polydoniti IC3, which gives the output of a symmetrical rectangular signal frequency 50HZ, followed by a buffer stage with Fet Q1-2, the driver stage and Q3-4 the power stage Q4-5, power transistors Q5-6, should be placed on a heatsink .. diodes Zener D2-3 protect the power transistors from voltage spikes produced by the transformer T1.
The transformer T1 are a simple power transformer with a medium shot, which is connected to the contacts of CO1. To use the wish, o T1, is placed upside down, with the secondary winding be used as primary, with the receiving means being connected to the positive battery voltage is 12V and the two other contacts are connected to the emitters of Q5-6, the connected to earth potential alternately, depending on the rate set by the outputs 10 and 11 of IC3. In this manner while flowing in the primary alternating current generated in the secondary alternating rectangular voltage 220V.
Using crystal oscillator ensures very good reference frequency 50HZ, and use a common crystal (CR1). For greater accuracy in parallel with C1, a variable capacitor CCH ensuring the adjustment of the frequency, in order to obtain the point P1 frequency 204.8 KIZ. It is evident that the output voltage at no-load is higher than the voltage under load. Also, the output voltage depends on the battery voltage. Thus for 14V battery voltage, the output voltage is increased by 10%, compared with the battery output voltage to 12V. If the converter works in load power 40 until 60W, then it can be used 2CH9V transformer. Various output values for battery voltage 12V transformer and 2CH10V.
