| Abstract |
The Solid-State Transformer (SST) is a key technology to support the massive deployment of Renewable Energy Sources (RES) and the electrification of several sectors. The Dual Active Bridge (DAB) is a promising topology to be used in Medium Voltage DC (MVDC) networks. However, depending on the modulation and the voltage ratio range, the DAB can present high reactive power and low efficiency at light loads. The leakage inductance is a key design parameter to optimize the overall converter performance. This paper presents a methodology to choose the leakage inductance for four mission profiles (PV, EV, residential and commercial) based on proposed weighted duration coefficients. The methodology considers a DC voltage variation and the change in reactive power and ZVS zones. The results show that the leakage inductance and the MFT design are different for profiles that operate mostly at low powers, such as EV. |
