This paper presents benefits of using 650 V SiC cascodes to realize a 1.5 kW single phase, continuous conduction mode (CCM) totem-pole, bridgeless power factor correction (PFC) AC/DC converter switching at 100 kHz. By exploiting the excellent switching and conduction performance of SiC cascodes, the compatibility with a 12 V gate drive and synchronous rectification of the full-bridge, a very high...
High-current, large-area single SiC JBS diodes rated at 650V-200A and 1200V-100A were fabricated on a 150mm platform that demonstrate a low VF of 1.5V. The diodes exhibit a specific differential resistance, Rdiff, sp, of 0.74 and 1.65 mΩ-cm2, respectively. The devices were tested with similarly rated Si-IGBTs and the reduction in switching losses and QRR evaluated. The high-current diodes have also...
