Simple PEEC model of complex DC power bus

PEEC model of DC bus is an accurate and effective way to analyze the transient process and EMI characteristic of converters. However, the PEEC model with normal partition method is very complicated. It is necessary to construct a brief and legible model. This paper proposes the partition rules and constructs the simple model of the DC bus in an H-bridge unit. Transient process analysis and two-port network analysis proved the simple model provides reasonable accuracy.
