摘要: A systematic control-loop design procedure for a multimodule converter system high-current, low-voltage applications is presented. small-signal model of the derived using PWM (pulse width modulation) switch and current mode control. The simplified to equivalent single-module model. implemented three-loop control strategy with secondary output filter developed. Significant improvements performance module-failure response are achieved additional feedback from intermediate stage. analysis controlled performed, focusing on effects local voltage closed-loop system. It shown that minimizes any detrimental effect resonance between power stage each module common filter. >
