I want to control dc motor 200Vdc 1A, can you suggest chopper circuit to drive this motor so I can control its speed,, thanks
 

These are quite high voltages. I doubt you will find circuit schematics laying around that easily meet the design parameters. Most circuits diagrams available are for smaller sized hobby motors as far as i know. I suspect you may need to buy a controller or design it yourself.

Are you just talking about the PWM part (along with the control electrics) or are you talking about a SMPS aswell capable of delivering 200V from a house socket ?
 

If you is using this 200Vdc motor with normal 220Vac, you can
use cheap triac or thyristor controller with diode bridge to
control speed of the motor.
