Pure Sine Wave SPWM Inverter 12vDC/220vAC 50 Hz- Help

[mohamedameen]

Hi all,

I need a working schematic design for a pure sine wave inverter using microcontroller or anything else.
Input voltage: 12v DC.
Output voltage: 220v AC.
Frequency: 50 Hz.
Power: 200 watt or larger.

Thanks in advance :razz:

Pure sine wave inverter problem

Hi all,

I'm working on a pure sine wave inverter using PIC16F877A, I used these topic as guidelines:
1. Sine Wave Generation with PIC16F877A: https://goo.gl/pJjTFG
2. Using the high-low side driver IR2110: https://goo.gl/6uMoV4

I have two problems:
1. When I give the circuit a 12v DC inputm it only gives me a 3v AC output!
2. I can't figure out how to design a suitable LC filter, I used a TCL-LC filter with two 30mH coils and a 150uF capacitor and it produces a 50Hz pure sine wave, but the amplitude of the signal isn't stable.

Could anyone help me?
