Abstract

This paper analyzes the influence of the amplitude and phase of the inverters output voltage on the power of the parallel system. A no-master-slave control strategy for paralleling inverter based on an interactive following method is proposed, which controls the amplitude of reference voltage and synchronize the phase of the reference voltage to share the active and reactive power by synchronization bus and CAN bus. The DSP (TMS320LF2407) is adopted to realize full digital control in this system. The experimental results demonstrate that the function of N+1 redundancy can be realized and the active and reactive powers are greatly shared
