Hi maharadga
I think you are going to construct the UPS version of the Sine Wave inverter. Maharadga, I would like to discuss about My experimental load test. According to taner's design, Pic16F876/877A pure sine wave inverter had been constructed. After that, I tested this inverter with variable loads. Firstly, I used 100 Watts light bulbs as the resistive loads. In this experiment, it can be defined that its' optimal Output power rating is nearly about 300 Watts. As it can be seen in my experimental results in Page 34. I also tested it with inductive loads with cooler fan. It is also Ok with stable sine wave. However, It is not reliable with capacitive loads test experiment such as my personal computer. I notice that taners' design is not reliable with capacitive load. It is not handle in capacitive nature in my experiments. Do you notice that? If you will test this condition, could you share your valuable advice and suggestions to me. I always look forward to discuss with you and Mr. Taner.

Hi californiajoe, jami007,
The above post is my experience from testing my experiment with capacitive loads such as my personal desktop computer. So we are going to the UPS version to reliable with computer, I think this fact is should be noticed that the output voltage fluctuation and wave shape deformed in capacitive load test experiment. If you notice that this point, How do you solve this problem? I will expect your valuable advice and suggestions.

i read about powering devices that are capacitive. like that desktop computer. the power source must be at least (3) times powerful than the total power of the total capacitive load's power to be run by the power source. the above is a rule of thumb. you said with bulbs, the effective power was around 300 watt. use a capacitive load of about 100 watt and observe the wave shape and output voltage stability. i hope to hear from you. peace.

Hi Taner,
I cannot get d circuit from either 4shared or mihd.net. Can you pls forward d circuit diagrams/resources to my e-mail on:
ibraheem.korede@yahoo.com.

Hi Taner,

Where can i get your schematic diagram and hex file.
i want to run my inverter in 60Hz.

Regards,
Mike

Hi,
i made my own sine-wave inverter with PIC16F876A,
here is a circuit and source code (for CCS PCWH):

Re: tz2l9

sorry could i ask , i use hi-tech C 9.80 or 9.83 could no be compile success , may i ask which compiler u are using . i was error that
#include <16F876A.h> and if i change to htc.h also wont work . may i know u are using hi-tech OR CCS ????

Re: pwm inverter schematics

one phase or three phase,which language do you want to use?

longcrystal · Mar 14, 2013

Re: pwm inverter schematics

Single phase. I just want try to compile the code but is error.

kabeer02 · Mar 14, 2013

which of the compiler are you working with?

longcrystal · Mar 16, 2013

MPLAB X i try to use 9.81 9.80 9.83 VERSION for Hi-tech C couldnt be able to compile....keep error .. just wanted to know..any ppl success this ..compile for the code.

kabeer02 · Mar 16, 2013

i used mp lab version 8.1 and i also use ccs compiler and they all work fine but what error message did you get?

longcrystal · Apr 4, 2013

since u success to build this sine wave inverter may u guide to me? about the component.... i not quite sure about the component

IND_CHOKE L1
Current Transformer CT TR2
inverter transformer TR1

can u take a photo for ur prototype design about these above component ? and can u show some specification value for these component . because i only know how to use the simple transformer such as 12-0-12DC to 230VAC ....but not quite sure about this schematic transformer component and inductor ..... hope i can get u reply for this helping ;-);-);-)

hi Mr.taner may i get u help about the component

i think CCS is different with HI-tech C....so i get u mean..should be use CCS..thank

The transformer used is 8v to 230v Ac.

and its tested ok

longcrystal · Apr 16, 2013

hi picgak ..u mean TR1 is 8-0-8 to 230V ???

how was the value for this two IND_CHOKE L1 ,Current Transformer CT TR2.....

I think you need to follow this tread from the beginning everything has been explained in details.
