avrsanju · Sep 29, 2016

hai,
after a lot of requests from the readers side, i am posting the sine wave ups source code written in mplab c-30 here.. this product is widely marketed by 2 persons in my country. as i am not a business man, i can share my know how to all without any charge. the another versions of these types up to 72 volt and transformer less hybrid modes are also developed and redy to share here. SOLAR zero drop charger, dspic based M.P.PT, and many more i have developed already and any body can download and use it...and one more thing, ask me for any droughts in my software.

After going through your above posted code i can smell that your above "charity" seems ill intended ... the code you posted is missing too much part and does not makes much sense , that said i feel that you are doing this just for advertisement purpose .. so dear if you really want to advertise then we already have such sections here in "edaboard" ... so please advertise in appropriate section .

powerteche · Sep 30, 2016

Which parts of the code should be removed, please give details. If those parts are removed will the Code work?
To which parts of the Code should the LCD program be added?

andre_luis · Sep 30, 2016

@avrsanju,
If your intention is to share a program with the programmers community this is really an appreciable attitude and we're grateful for that, however assessing technically your code I have to agree that although it could have been worked in your experiments, there are several constructive aspects that make it somewhat unintelligible so that you could make a clean on it just before releasing it in terms of good practices of programming. Just citing some of them: There's the fact you have not removed the commented parts of the code, you have not structured the code in functional hierarchical layers (such as having encapsulated all Initializations within a Init() function, you have put several inline evaluations within main(), you did not parametrized some numerical values, etc...

@powerteche,
Your question is unclear, this was not mentioned before, so are you asking for help to improve this code ?

avrsanju · Oct 1, 2016

sir,
the code part i shared here is to get some idea about pwm H bridge init and manual smapling of adc over sinewave and sinetable pop-up using modulate function. and the commercial part is not added here,only with an intention that, while i start doing this concept,i dont get any samples,instructions,trick,,etc,so any body is willing to do such a project,the root for the destination only i posted here.it may look chunky and nesty,,but still countless numbers are working in field last 2 years. thank you for your guidelines and replay.

andig · Oct 13, 2016

Hi avrsanju,

Thanks for posting your code. It can be a reference for building sinewave inverter.

However this doesn't take the design much further than the good old 16F73 inverter. What I dislike of the 30F2010 is a mere 512 bytes of RAM. Given it to be a 16 Bit controller that's too low. Still it is the cheapest and the cheapest always wins. Rather than taking the crest factor as granted it is possible to do RMS on the fly, dsPIC and make good use of its integer number crunching ability than a standard micro.

I appreciate your effort though.

madhu hegde · Oct 17, 2016

Hi avrsanju.

i need of help for lcd display with 4 line ... interface for my existing products .. can you help me ?

avrsanju · Oct 31, 2016

which compiler? which version?...a lot of header files are there in internet..you can use it customized.if you want a 2 wire lcd,in ccs or in c30 i can post it here..

student_sound · Dec 4, 2016

Hi Mr Sanju !

is your code have funtion ? Auto detect of LCD and LED. Can change between LED / LCD while the system is powered.

hai,

can someone post the schematic circuit diagram for this sine wave ups source code below.
