Is the wave shape at no load square? and if so how then can you get a pure sine wave shape at no load because i have seen some design that produce pure sine shape at no-load condition,
Regards
hi every one, to those who have made the prototype of this project i ask what is the output wave shape like under NO-LOAD condition? is it pure sine wave?
regards
hi Tahmid,
this is about the last stage and most important of my request thus--output regulation.
please can you propose a control algorithm and include the implementation C-code in my open loop
code which you can access in the post #59 .i will appriciate every effort to get this
aspect of the...
HI ALL,
I will suggest you generate just two spwm from the PIC ---CCPR1 &CCPR2 directly into the driver to the MOSFETS without the steering
logics in tanners work. i hope this will simplify the schematics but with little additional software overhead.
regards,
hi Tahmid,
thanks for your short tips. as for your new inverter design i would suggest
1----you move to PIC18FXXXX series because of their multiplication capabilities
2----try syncronous rectification(boost) charging algorithm , people on the forum might suggest to us how to implement this...
Hi Tahmid
Can you please upload your schematics so that we can all make well informed remark and contribution on it.
We can equally learn one or two things there.I hope also you will respond to my overload/short circuit request
Regards,
Hi Tahmid,
I think we can address the issue of overload/short circuit protection, can you suggest a reliable/effective
protection for a mosfet-based inverter. i need practical circuit with short explanation of how it works.
What is the difference between overload and short-circuit?. is...
Hi Tahmid,
Please clarify the following two questions concerning generation and implementation of sine wave table
before we move to the next level.
1------>In a typical sine wave inverter design, must the peak amplitude be equal to the swithing period?
if not, what value of peak...
HI TAHMID,
When i run the setup.exe, the program start installation up to a point and stop. My OS is windows vista and i dont think i need net.frame
is it not?. the error reported is "sine wave misc stopped working". windows then adviced me to contact the manufacturer.
hi Tahmid,
idownloaded your software sine wave misc. but upon installation it reported error " sine wave misc.stopped working" and so i can evaluate it
pls. check and correct error.
Hi Tahmid,
Thanks alot for this write up, it is well explained. i will read it very well before i ask more question but first -:
1. must the amplitude of our sine wave be always equal to our switching period? if not can any amplitude of our choice
be use? if yes then what will inform our...
