RICHARDSON RFPD Wolfspeed 200 kW CRD200DA12E-XM3, 250 kW CRD250DA12E-XM3 and 300 kW CRD300DA12E-XM3 three-phase inverters enable more than twice the power density of comparable silicon-based designs, with greater than 98% efficiency. Switching frequency is set by the user, up to 80kHz. The reference designs demonstrate the best-in-class system-level power density and efficiency obtained by using firm’s XM3 power module platform. The XM3 power module platform is optimized for SiC MOSFETs in a high-density, low-inductance footprint, which reduces system-level losses and simplifies the overall system design.
