XM3 Power Module Platform

Wolfspeed and Analog Devices (ADI) combine market-leading silicon carbide modules and isolated gate drivers to deliver high-efficiency and high-reliability system solutions across industrial, energy, and automotive applications. The XM3 platform is a perfect fit for demanding applications such as motor and traction drives, electric vehicle fast chargers, uninterruptable power supplies (UPS), and industrial automation and testing.

With half the weight and volume of a standard 62 mm module, the XM3 power module maximizes power density while minimizing loop inductance and enabling simple power bussing. The XM3 companion gate driver utilizes Analog Device’s ADuM4135 integrated digital isolator and gate driver IC with 2 W isolated power supplies, maximum switching frequency of 80 kHz, differential signaling for EMI/EMC immunity, and isolated frequency-encoded NTC feedback.
