    Hi friends,
    I am new to this forum. I am working on 1PH SCR based DC drive. can anybody suggest the right controller for the same?
    The controller have following jobs to do,
    1. Sence the synch pulse,
    2. Generate the PWM mutli pulsing,
    3. Take care of faults like fild loss, external fault,
    4. Faults indications,
    5. RPM metering

    Which controller series I should use PIC OR AVR???
    I think about AVR Atmega it right to use it...(I never worked on Fermware in past)...

    Either microprocessor family will do the job. You are better off selecting the external components and circuitry, and then selecting the microprocessor based on number of I/O pins requires and things like A to D channels.

    A thing you may be interested is that Atmel (AVRs) offers the appropriate software for free online whereas Microchip (PICs) does not.

    If you are interested in looking into AVR, you can go to and search on keyword AVRSTUDIO4. You will find the FREE software download. Install it on your PC and take a look at all of its features. I think you will quickly be impressed that such a powerful software development tool is available for no cost.

    The most current version is AVR Studio 4.15 (build 623).
