Abstract

Synchronization effects and performance degradation of a distributed inverter built with several phase-leg power electronics building block (PEBB) modules controlled with a space-vector pulsewidth modulation (SVPWM) strategy are presented in this paper. Under the control of the distributed SVPWM strategy, the inverter PEBB modules generate their target output voltage vectors separately, operating simultaneously with the command of the synchronization signal sent by the master module or the upper level controller. When a synchronization error exists, the line-to-line output voltage will contain some noncharacteristic harmonic components. This paper systemically analyzes the impact of synchronization error on the system performance. Conclusions are derived from the double Fourier analysis, MATLAB simulation, and experimental results.
