Abstract: Related to the developing tendency of on-vehicle auxiliary converters,parallel operation makes itself high-lighted.For auxiliary converters paralleled,the drooping of amplitude and frequency for the balanced distribution of active and reactive power respectively features more merits over the conventional drooping approach.However,such novel drooping approach shares the shortcomings of slow dynamic response,as well as limited drooping parameters,etc.To overcome the shortcomings above,this paper proposes a revised whole-cycle adjustable drooping approach,which is combined with a novel power calculation process without long-delay low-pass filter.The approach proposed is capable of improving the dynamic response greatly.What’s more,this paper comes up with a compensation mechanism composed of resistance voltage drop and phase-lock loop,which shows brilliant performance during the suppression of voltage output drop after increasing drooping coefficient with different converter parameters.In the last part,the proposed above is subjected to simulations and experiments for the verification of effectiveness.
