Beschreibung

The HVD3GD evaluation board is a dedicated two-board gate-drive solution for the 3.3 kV, 7 mΩ MSCSM330AM07CD3NG mSiC™ half-bridge module in the 62 mm D3 package. A cantilevered mechanical footprint mounts the board set directly over the module gate and source terminals for drop-in evaluation. Control and status signals cross the primary isolation barrier over a fiber-optic link, giving 6 kVworking isolation, low coupling capacitance, and high CMTI in electrically noisy medium-voltage environments. A dedicated Power Board generates independently isolated bias for the high-side and low-side channels through separate isolation transformers, supporting the gate-charge demands of large 3.3 kV modules at switching frequencies up to 50 kHz. Configurable gate-drive rails and hardware-based half-bridge protection including DESAT with soft shutdown, shoot-through interlock, deadtime generation, auxiliary and gate-drive UVLO, and per-channel fault flags with latch/reset all implemented on-board rather than in firmware.
