N2 - In the application of electric vehicle battery systems,an auxiliary power module with wide range is required to convert the high-voltage battery pack to the low-voltage auxiliary battery. A two-stage converter with wide-range is implemented with silicon carbide power devices in this paper. The first stage is a boost converter and the second stage is a full-bridge resonant converter. According to the output voltage range of the system,the corresponding output voltage range through pulse width modulation control is designed for the first-stage converter. In this way,the second-stage converter can be operated through near series resonant frequency control,the magnetizing inductance can be designed to be large to reduce circulating current,and with the synchronous rectification technology of the secondary side,the overall system efficiency can be improved. In this paper,a prototype with input voltage (VH) 220-450 V,output voltage (VL) 9-16 V,and rated power 2.5 kW is built with a digital signal processor TMS320F28335. As the experimental results shown,the maximum efficiency of the system is 97.74% with VH = 450 V and VL = 9 V at 20% load condition.
