Rangkaian Inverter 12 - 220 Volt

Pengertian Inverter

Inverter is a series of functions to change the dc voltage into ac voltage.
One of the purposes inverter that is popular enough to raise the dc voltage of 12 to be 220 Vac. after the change in voltage from 12 Vdc into 12 Vac, and the increase in the voltage transformer using a 220 Vac.

Simple Circuit of Inverter 12 vdc to 220 vac

following is a circuit of simple inverter. although quite simple, but this series is able to work well to change the dc voltage coming from the 12V battery into 220 Vac.

List of components Inverter :
C1, C2 68uf/25v
R1,R2 10 Ohm, 5Watt
R3,R4 180 Ohm, 1watt
D1,D2 5 A atau lebih
Q1,Q2 2N3055
T1 Transformator 11V,CT

important:
transistor Q1, Q2 2N3055 must be provided in the cooling fan

The power output is determined by transformer and power transistors T1 & T2. Assume a transformer of about 15A and the chosen transistors of IRF 540 (22A) type, the inverter can supply about 250 watts with the parts shown. If you are good with electronics all you have to do is replace the IRF 540 and transformer accordingly for more output. It is imperative to mount T1 and T2 on large coolribs. If you intend to beef everything up with a couple kilowatts a standard (5″) cooling fan will also be required
