Abstract

This paper proposed a dc voltage control for inverter interfaced dual active bridge converter. This converter is used in SiC based on-board charger for electric vehicle. The inverter interfaced dual active bridge converter has a dc link as a middle stage of AC/DC conversion. This dc-link voltage is unstable without control. Especially in applications like vehicle-to-load (V2L) applications, the converter is required to operate under both 120-volt ac load and 480-volt ac load so the vehicle can export power to external loads. The large variation of dc link voltage requires a robust general dc voltage control to guarantee a safe operation of load change. This paper analytically derives the small-signal model of the inverter interfaced dual active bridge converter at wide range of operating point. Based on the small-signal model, a robust dc voltage control is proposed to adapt to the wide range of dc link voltage. The proposed dc voltage control is verified by a 25-kW SiC based inverter interfaced dual active bridge converter prototype.
