Abstract

Performance analysis of three-level active neutral point clamped (ANPC) inverter with 650V SiC MOSFETs by ROHM is presented with a new switching pattern that utilises the active rectification capability of SiC devices. Performance analysis of the converter with 700V DC link and 230Vrmsgrid voltage are presented for different switching frequency, device case temperature and load conditions. The switching frequency is varied from 10kHz to 80kHz at four different output power and four different heat sink temperature conditions. The experimental results show that the converter can maintain high efficiency under wide load, frequency and heat sink temperature conditions. Robust performance of SiC devices can lead to reduction in passive component size, by utilizing high switching frequency and heat sink weight and volume by operating SiC at higher case temperature conditions.
