Abstract: High-power IGBTs are widely used in new energy conversion, rail traction, and high-voltage power transmission. Their characteristics—high current-carrying capacity, fast switching, parasitic sensitivity, and concentrated thermal dissipation—demand precise control of gate charging and discharging, high-frequency reliability, and strict synchronization in multi-device parallel operation. To address these challenges, this paper proposes a modular drive technology that integrates standardized modules for push-pull output, isolation protection, and local safeguards. Through dynamic gate parameter modulation and coordinated interlock mechanism, it achieves synchronization drive deviation <20 ns, parameter adaptability across multiple scenarios, and interlock response within microseconds.
Key words : high-power IGBT; modular drive technology; gate control; interlock protection
