Application of WBG Power Devices in Future 3-Φ Variable Speed Drive Inverter Systems "How to Handle a Double-Edged Sword"
(2020)2020 IEEE International Electron Devices Meeting (IEDM)Latest research results on three-phase wide-bandgap (WBG) inverter systems with full-sinewave output voltage filtering are reported. A new soft-switching modulation scheme for two-level 1200 V SiC inverters is described. Furthermore, a new Figure-of-Merit for determining maximum multi-level (ML) bridge-leg efficiency is defined and low-voltage GaN devices are evaluated considering ML flying capacitor (FC) and multi-cell inverter structures. ...Conference Paper -
