ABSTRACT:
By using the on-state forward voltage drops of the power switches to measure phase currents, and by using diode logic to sense the voltage drops, it is possible for a single voltage comparator to perform the current regulation function for an entire power converter. Current regulation is obtained in drives using either overlapping or nonoverlapping current conduction for excitation of the motor phases. A thermistor compensates for offsets and for temperature sensitivity of the power switch voltage drops.
