摘要

The authors present comparisons of the performance of three types of dynamic current distribution control strategies for power converters connected in parallel. The controls considered are static ramp pulse width modulation (PWM) control (SRPWM), dynamic ramp PWM control (DRPWM), and peak current PWM control (PCPWM). All of these controls are capable of dynamically distributing the total output current among converters in the system, although there exist several different features in their performance characteristics. The comparison is concentrated primarily on the aspects of controller implementation, system stability, transient behavior, and deviation of current distribution from the desired value.
