The Trace Technologies 1‑151529‑02 is a high‑voltage IGBT gate driver board designed to interface power transistors in industrial motor drives and inverter systems. Common failure modes for this class of drivers include isolated input pin damage, over‑current on the output channels, or degradation of the internal DC/DC converter and protection diodes; overheating can also cause latch‑up of the driver ICs. First‑check diagnostics: verify that the supply voltage to the board matches the specified ±48 V (or as per datasheet), inspect for any visible burn marks or cracked PCB traces, and use a multimeter to confirm continuity on the gate drive outputs while monitoring output current with an oscilloscope if available.[oss-gpt-20b]
