This paper describes the design and performance of a 6-kW, full-bridge, bidirectional isolated dc–dc converter using a 20-kHz transformer for a 53.2-V, 2-kWh lithium-ion (Li-ion) battery energy storage system. The dc voltage at the high-voltage side is controlled from 305 to 355 V, as the battery voltage at the low-voltage side (LVS) varies from 50 to 59 V. The maximal efficiency of the dc–dc converter...
A bidirectional isolated dc-dc converter manages the power flow between an energy storage device and a dc bus with functions of galvanic isolation and voltage matching. Research and development of these converters focus on improving efficiency and power density. This paper presents and compares various configurations of bidirectional isolated dc-dc converters. It also illustrates the performance of...
This paper describes the design and operation of a 6-kW, full-bridge, zero-voltage switching, bidirectional isolated dc-dc converter for a 2-kWh lithium-ion (Li-ion) bank that is considered attractive as an energy storage system for applications to photovoltaic generation systems ranging from 10 to 30 kW. The dc voltage at the high-voltage side of the converter is controlled from 305 to 355 V as the...
