Re: Re: 3 phase AC drive using LPC2136 - Cool Dude - Jul 13 23:58:19 2008
hello Mukund Deshmukh,
I had some doubts in the caculation part of the algorithm. Can i know which
application datasheet have you been using for you code development.
I've been using AN955 from microchip in which when i calculated the "vector
angle" value i had some issues. The issue is I wanna know whether Vs is
suposed to lie in a particular sector for a single Ts and is supposed to
increment to the next to sector in the next Ts(ie according to datasheet am
i supposed to get a carry according to the datasheet). or is it ok if the Vs
stays in the same sector for multiple Continues Ts (if the calculations says
so) and then increment to next sector when the carry is developed as the
datasheet says...

I have decided to use LPC938 and not LPC2136, because of PCB space and cost.

finding it difficult to get IR2136 as my driver IC. None of the distributors
encourage me in getting a few No.s of ICs. .
Wthat about PWM and ADC is worryin you. Dont have them in ur controller.
Raj
IR2133 is available in Mumbai.
My only worry is about performance of LPC2136 in noisy environment (e.g.
switching frequency of 20Khz.)
and NOT PWM, ADC
