Analysis of SiC and SiC-Cascode MOSFET in the design of power electronics converters for more electric aircrafts

<span>Wideband gap (WBG) semiconductors have developed rapidly in recent years, enabling greater efficiency and power density the design of electronics converters for several areas application. In this sense, work analyzes specificities silicon carbide (SiC) technologies their cascode topology (SiC-Cascode), operating at high switching frequencies. The are performed using a Boost converter designed conversion systems more-electric aircraft (MEA) context, where alternating current (AC) can operate fixed frequency (115V/400Hz), or variable (115V/360-800Hz), such as observe Boeing 787, direct (DC) system with DC bus 400 V +/-270 normally used. To validate project, computer simulations were 1.0kW prototype was built laboratory. performance analyses demonstrates that 97.5% is achieved 500 kHz frequency.</span>
