    I want to make a three phase analogue thyristor control dc drive. So pl. help if there is any circuit for this drive.
    Thanks. surinder

    Provide as much information as possible please.

    What DC control voltage do you have available? Can you use triacs or does it have to be thyristors? What load do you want to switch (power)? What's the 3-phase voltage (country)?

    Dear Sir,
    I am located in India and supply voltage is 3 phase 440v here. I want to make a analouge dc drive for 10 hp dc motor and its armature voltage is 440 v dc.So pl.suggest any circuit which we can use for firing of thyristors (used with single quadrent configuration) .
    thanks.

    Small power variable speed DC motor drives are readily available off the shelf with all the "bells & whistles" you might need - why do you want to build your own from scratch?
