400V SiC MOSFET empowering three-level topologies for highly efficient applications from motor-drives to AI
Year: 2025
Type: article
Abstract: The introduction of 400 V SiC MOSFET technology bridges the voltage range gap between 200 V medium-voltage MOSFETs and 600 V super-junction MOSFETs. This technology is characterized by low switching losses and low on-state resistance, making it suitable for 2-level topologies in 120 VAC or 300 VDC systems or 3-level topologies with typical input voltages ranging from 180 VAC to 350 VAC or 400 VDC to 600 VDC. The technology concept is presented, and its efficiency and power density gains are demonstrated through measurements on test boards representing a 3-level ANPC general purpose inverter and a 3-level FC PFC for highly-efficient power supplies.
