Abstract
Fuel cell electric vehicles (FCEV) are an emerging clean energy vehicle. In order to meet the requirements of the complex input and output features of the DC-DC converter for FCEV, a compound input/output feature control system was proposed which is based on the three-closed-loop control system consisting of output constant voltage, output constant current and input under-voltage, and a compound automatic controller was employed to dynamically choose the method to control the feature regulating signals. The mathematical model was built for the compound control system, and its working principle was analyzed in detail. The model was simulated with the software Simulink and the results were validated by the experiments. Simulation and experiment results verify the effectiveness and feasibility of the control system. The method enables the FCEV to control the external features of the input and output of the converter. The method has been applied to the 90 kW DC-DC converter, and proved to operate with reliability.
