In-stock availability and full design support capabilities for three inverter reference designs from Wolfspeed is announced by Richardson RFPD.

The 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 80 kHz. The CRD200DA12E-XM3, CRD250DA12E-XM3 and CRD300DA12E-XM3 use the CAB400M12XM3, CAB425M12XM3 and CAB450M12XM3 modules, respectively, as well as the CGD12HBXMP gate driver.

These reference designs demonstrate the system-level power density and efficiency obtained by using Wolfspeed’s new XM3 power module platform.

The XM3 power module platform is optimised for SiC MOSFETs in a high-density, low-inductance footprint, which reduces system-level losses and simplifies the overall system design.

Applications include high-power density new product development, high-frequency converters, vehicle traction inverters, active front ends, uninterruptible power supplies, industrial motor drives, energy storage, grid-tied distributed generation (solar and wind), and smart-grid and flexible AC transmission systems.
