Abstract In this paper,several control strategies of the non-isolated interleaved parallel full-bridge controllable current source inverter with a common DC are analyzed and compared with each other.Analysis of the harmonic structure of the inductor current under the control of carrier-based interleaved unipolar frequency-doubling SPWM is carried out.Thus the maximum ripple of a single inductor current within the converter is figured out in the interleaved condition according to the operating mode,and then compared with that in the synchronized condition.This provides a guideline for the design of the inductor.The simulation and experiment are carried out to verify the correctness of the analysis.

Key words： Non-isolated inverter parallel current source inverter control strategies unipolar frequency-doubling
