Galvanic isolated gate driver

NCV is a high−current single channel IGBT driver with internal galvanic isolation, designed for high system efficiency and reliability in high power applications. Its features include complementary inputs, open drain FAULT and Ready outputs, active Miller clamp, accurate UVLOs, DESAT protection, and soft turn-off at DESAT.  · With 26V maximum gate-drive output voltage and optional separate turn-on/turn-off outputs or integrated active Miller clamp, STMicroelectronics’ STGAP2S single-channel galvanic isolated gate driver can control silicon-carbide (SiC) or silicon MOSFETs and IGBTs across a range of switching topologies. NCD(V)/3/5/6 are high−current dual-channel isolated IGBT gate drivers with or 5 kVrms* internal galvanic isolation from input to each output and functional isolation between the two output channels. The device accepts V to 20 V bias voltage and signal levels on the input side and up to 32 V bias voltage on the output www.doorway.ru: Isolated Dual-Channel IGBT Gate Driver.

NCV is a high−current single channel IGBT driver with internal galvanic isolation, designed for high system efficiency and reliability in high power applications. Its features include complementary inputs, open drain FAULT and Ready outputs, active Miller clamp, accurate UVLOs, DESAT protection, and soft turn-off at DESAT. The galvanically isolated gate-driver ICs also provide strong, up to 10 A gate-drive currents for excellent power-switching efficiencies. Package options include small LGA as well as DSO 8-pin to pin variants. These isolated gate drivers leverage ADI’s proven iCoupler isolation technology combined with high speed CMOS and monolithic transformer technology to enable ultralow propagation delay without sacrificing common-mode transient immunity (CMTI) performance. High pulse fidelity architecture enables motor power efficiency to meet new required efficiency levels, and superior timing performance stability reduces voltage distortion, as well as harmonic and output power content on solar inverters.

with an ADuM isolated gate driver, which provides much higher drive then safety isolation may not be necessary, but galvanic isolation is a. In applications using SiC/GaN high-voltage semiconductor devices under hard-switching operation, galvanic isolation is a common requirement for safety and. Jan Texas Instruments' UCC galvanic isolated single-channel gate driver is designed for SiC MOSFETs and IGBTs up to 2, VDC operating.
