Description
Summary:In this paper, a Series Partial Power dc-dc Converter (S-PPC) is compared with Buck-Boost Full Power dc-dc Converter (BBFPC) as an interface between Battery Energy Storage System (BESS) and dc microgrid. To achieve a fair and accurate result, several Key Performance Indicators (KPI) are considered. non-active power processing, Component Stress Factor (CSF), and efficiency of both converters are compared at three points of battery charging (3 kW,2 kW, and 1 kW) and three points of battery discharging (3 kW, 2 kW, and 1 kW) application. Due to full power processing in BBFPC, higher non-active power processing, and CSF occurs in all operation points of the converters. Furthermore, the efficiency estimation results show that S-PPC has higher efficiency than BBFPC in all operation points, which was estimated using PSIM thermal module. Datasheet parameters of all the components are imported to the software library to simulate both converters. The simulation results confirm theoretical calculations and predictions.
