N2 - This paper presents a controller with duty-cycle dynamic distribution within parallel-connected PFC converters based on average-current control strategy, which can distribute the control duty-cycle automatically for each parallel-connected PFC converter to realize current balance by the difference from its reference current, and it can decrease and even eliminate the disturbance resulted by current-balancing process to total input current and output voltage. Moreover, a simple method is presented to interleave the currents of parallel-connected converters, and it can minish the size of filter and increase conversion efficiency based on only a single DSP. Taking three PFC modules in parallel for example, the scheme presented in this paper was validated with experimental results, and it would be a desirable digital solution for parallel-connected PFC converters in large power application.
