Abstract
Isolated direct DC/DC converter topology structure for fuel cell system includes: Boost converter topology structure and bidirectional full-bridge converter topology structure connected in sequence. Input of the Boost converter topology structure is connected to fuel cell, and output of the Boost converter topology structure is connected to other key components of the fuel cell system and input of the bidirectional full-bridge converter topology structure. Output of the bidirectional full-bridge converter topology structure is connected to power cell. Usage of the Boost converter topology structure and usage of the bidirectional full-bridge converter topology structure change under different operating states of the fuel cell system. Based on insulation performance and high efficiency of the fuel cell system, the usage of the Boost converter topology structure and the usage of the bidirectional full-bridge converter topology structure change. Low efficiency caused by DC/DC converter with single isolated topology structure is effectively overcome.
