Abstract
A wide input range multi-stage converter is
proposed with the fuel cells and supercapacitors as a hybrid
system. The front-end two-phase boost converter is used to
optimize the output power and to reduce the current ripple of
fuel cells. The supercapacitor power module is connected by
push-pull-forward half bridge (PPFHB) converter with coupled
inductors in the second stage to handle the slow transient
response of the fuel cells and realize the bidirectional power flow
control. Moreover, this cascaded structure simplifies the power
management. The control strategy for the whole system is
analyzed and designed. A 1kW prototype controlled by
TMS320F2808 DSP is built in the lab. Simulation and
experimental results confirm the feasibility of the proposed two stage
dc-dc converter system.
