I wish to build an adjustable DC power supply to supply the field winding of a DC motor. The DC power supplies available in my lab are not suitable because they either have limited voltage or current supply. My aim is to build a DC power supply that is able to supply 2A at 210VDC. The current supplied by the DC power supply must be as constant as possible (e.g. no ripples). What options that I have?
