4.5 kV and 6.5 kV IGBT gate driver cores

May 26, 2014 // By Graham Prophet
IGBT gate driver manufacturer CT-Concept Technologie GmbH, a Power Integrations company, has announced its 1SC0450V single driver core for IGBT modules with blocking voltages of 4.5 kV and 6.5 kV. It enables IGBTs to be paralleled using only one driver core, which reduces system size and increases reliability.

A new member of Concept’s family of high-voltage gate driver cores, the 1SC0450V is based on the company’s SCALE-2 chip set and a partial-discharge-free, low-coupling-capacitance, high-voltage DC-DC transformer. An advanced transformer design allows test voltages up to 10.4 kVRMS and a partial discharge extinction voltage of 7800 Vpeak. The driver core measures 60 mm by 90 mm long with a height by the DC-DC transformer of 27.50 mm. Concept’s 1SC0450V gate driver cores are suitable to drive all 4.5 kV and 6.5 kV IGBT modules currently available on the market. Target markets include traction and other high-voltage applications.
