MULTI-PHASE DC-TO-DC BUCK CONVERTER WITH MULTI-PHASE CURRENT BALANCE AND ADJUSTABLE LOAD REGULATION |
摘要 |
To balance the current of individual channel as well as regulate the output voltage for a multi-phase DC-to-DC buck converter, the converter output voltage is sensed and compared with a reference signal to produce a first error signal serving as first control signal for PWM signals of the converter and the channel currents are sensed, summed, averaged and subtracted to produce second error signals that are further modified by saw-tooth wave signal to produce second control signals for the PWM signals. Moreover, the reference signal is controlled by the summed channel currents for adjustable load regulation.
