Sinewave Inverter With Pic

[alejandro]

I am looking for a project of a dc/ac sinewave inverter with pic, if anybody can help


Thanks

i'll scan the pages next week for you.
 
 
 i hope this code will be useful to you

[alejandro]

Thanks a lot picstudent, I´ll test it.

[Kabron]

Look also Microchip Application notes for PIC based UPS project.

[alejandro]

thanks too. I saw that project but I m looking for somethin using picbasic.
I 'm fighting with some designs with push pull and a 16f73 but couldnt get a good
waveform

[Kabron]

U can use MC3PHAC chip from Freescale(free samples!) with PIC as master controller. I now developing drive for high-end vinil turnable with this combination. If any interest arise I'll upload the details.

[alejandro]

Yes, please up load it

thank you

[Kabron]

OK Just wait a while I clear some shit.

One more reference on circuitry of the inverter:

[Kabron]

Not cleared yet. Working with real MC3PHAC withouth powerstage. Any questions welcome.

[alejandro]

thanks a lot for share your project Kabron

i have a product and software with pic 16F72 , but i cant share it bcause its my buisness product.
pure sinewave 50HZ with pic16f72.

I made a sine wave inverter with PIC16F876A,
Input: 12V DC (10-16V), Output: 220V AC,50Hz, Output power: 500W
Here is the CCS C code and circuit of the sine wave inverter:

only sine and modified inverter simulation with proteus. only video  direct download

Hi picstudent
Can you upload scanned documents from magazine?

Thanks

Hello
Anyone has the complete list of the parties, because in the Schematic some values are missing.

Thanks

Hi, sohel, I want to know much will it cost to the investor but output at 60Hz

thanx for sharing Schematic
but there are some values missing and connection of some comparator are also missing can u upload the complete schematic plz

Atmel AVR model ATtiny26 has nice hardware built-in PWM generator for driving bridge's circuits with dead-time generation. I think that it can be good platform for your project.

[sohel]

there are many wayes to build sinewave inverter without microcontroller. some cmos or ttl and eprom, dac

for who want to see circuit with pic16f72.

u need to get topology thats it.

[Walkura]

I fully agree with Sohel on this .
Although microcontrollers offer the possibility of pimpy add-ons they are by no means needed .
You can generate that pwm easily with a few opamps or even with some standard pwm generator .
For instance the setup for class d audio pwm generation .
Even the good'oll SG3525 can generate that pwm and is capable of adjusting the dutycycle according to your feedback loop .
Although microcontroller might seem the way '
you should ask yourself the question isn't programming just a longer way to the same goal .
To be honest i wouldnt be suprised when a analog setup outclasses the microcontroller bigtime in speed of feedback etc .
Afterall there wont be any calculations to be done no capture and compare you just feedback your output to your pwm generator (isolated ofcourse ) the reaction is instant (almost)
Maybe it sounds *stoneage* but you should be able to do that with a few opamps and a handfull of discrete components

Can anyone explain the working of the above circuit ...plz

Hi sohel,

The hardware schematic you provided is the one many people are using india,I know of many companies here including me who developed software around this hardware....in this I am using Spwm frequency of 6.4Khz.This design also uses BOOST PFC charging by switching lower mosfets @ 15Khz.

[sohel]

please help us with ur firmware and idea.  thanks.

[alien]

I am extremely sorry as I can not share the code and other details because its a commercial design with some commitments,but still I can give some hints...bythe way ...Sohel as you already own the code then you should be well aware of how this design works?
