High voltage IGBT gate drive unit

2 June 2004 Power Electronics / Power Management Programmable Logic

Westcode Semiconductors has released to market a high voltage IGBT gate drive unit (GDU) designed to complement its range of high voltage press-pack IGBTs and standard IGBT modules. The C0030BG400 is a single channel 30 A peak-rated driver suitable for low and high side applications. With a DC link voltage of up to 3,5 kV (5 kV available on request) and with dv/dt immunity of over 100 kV/µs, this GDU performs all of the necessary supervisory functions including under voltage lockout and SCSOA protection with user configurable response and feedback. The unit requires a simple 15 V d.c. power supply and features fibre-optic command and feedback signals.

It is capable of driving virtually all IGBTs, including the company's range of press-pack devices rated up to 5200 V and 1500 A, at frequencies from DC up to 20 kHz. Options include standard variants set up for use with each of Westcode's range of Press-Pack IGBTs and the core module for integration into end user PCBs.
