| Abstract |
Series-connected MOSFETs with lower voltage ratings can be an alternative for single high-voltage switches. In this paper, we provide a comparison of two switch configurations for soft switched power converter topology targeted for 1400V DC grid. The first configuration is a single switch rated at 1700V whereas, the other is a series connected two MOSFETs rated at 900V. A buck converter with 1400V and 700V as input and output voltages respectively is taken as a case study. Triangular current modulation (TCM) is used to ensure zero voltage switching (ZVS) at turn-on for all the switches. The analysis shows that the series switch configuration can have much lower overall losses than the single switch configuration. |
