Dual-channel 4.5 kV IGBT-driver with transformer-based signal interface

CONCEPT’s new IGBT drivers are based on the company’s proprietary SCALE-2 ASIC technology, which integrates all required functions: driving, monitoring, status acknowledgement, isolated voltage supply (DC-DC converters) and isolation of all signals between the control and power sections. This approach also allows for full design flexibility when considering protection strategies, interface circuitry and the partitioning of the power inverter. UL-compliant, 2SC0635T gate-driver units provide isolation according to IEC 61800-5-1 and IEC 60664-1.

Devices can be easily configured for parallel operation, and feature Advanced Active Clamping as well as short-circuit protection and under-voltage lockout. Comments Wolfgang Ademmer, CONCEPT’s CEO: “The 2SC0635T is the first commercially-available 4.5 kV IGBT driver to feature transformer-based signal isolation and an integral DC-DC converter. This enables engineers working on medium-voltage inverter applications such as traction, HVDC, STATCOM and wind-power converters to benefit from a compact, reliable design.”
