anybody can help..........for implementing loops

[RATAN ROY]

hi,
ineed to develop a high stability power supply (long run PPM less than 100) rating 170A/100V.i need to use to loops,one voltage loop and one current loop.but i have only DAC output.How can i go ahead,please..........as soon as possible

In two loops, you have current loop as the inner loop and voltage loop as the outer loop. The output from the voltage contoller (ie. from the outer loop controller) becomes the reference of the current for the inner loop.

what type of controller you are using?
