Four Quadrant Power Supply Provides Any Polarity Voltage & Current - 01/08/04 EDN-Design Ideas: A conventional power supply operates only in the first quadrant; positive-voltage output and current are sourced to a load or, with a deliberately miswired output, statically in the third quadrant as a "minus" supply. The conventional supply cannot, however, operate in either the second quadrant as an adjustable load for a minus supply,.....(design idea added 1/05)
