Power Integrations Expands Gate Drivers to Support 1700 V IGBTs

May 16, 2017 by Power Pulse1595211359

Power Integrations today announced an expansion of its SCALE-iDriver™ family of galvanically-isolated single-channel gate driver ICs. The new devices support IGBT blocking voltages up to 1700V, which are generally used in 400Vac and 690Vac line applications. They are also suited for the latest three-level topology photovoltaic inverters and for photovoltaic arrays leveraging the new 1500Vdc bus standard. The expanded 1700V SCALE-iDriver family allows OEMs to use the same highly integrated, safe and reliable driver technology across a range of solutions.

1700V SCALE-iDriver ICs, optimized for driving both IGBTs and MOSFETs, combine Power Integrations’ pioneering FluxLink™ magneto-inductive bi-directional communications technology with its SCALE™ power device driver technology. FluxLink eliminates the need for unreliable opto-electronics and the associated compensation circuitry, thereby enhancing operational stability while reducing system complexity, and SCALE technology incorporates all key gate driver functions into an ASIC, reducing size and improving reliability while simplifying design. Innovative eSOP package features greater than 9.5mm of creepage and a CTI of 600, ensuring substantial operating voltage margin and high system reliability.

1700V SCALE-iDriver ICs can be operated from -40 to +125 degrees C and at frequencies of up to 75kHz. The family meets the upcoming requirements of IEC 60747-17 and VDE 0884-17. Devices feature desaturation (short-circuit) protection with Advanced Soft Shut Down (ASSD) functionality, providing reliable and easy-to-implement protection to the power switch.

Comments Michael Hornkamp, senior director of marketing for high-power products at Power Integrations: “With the launch of our new 1700V SCALE-iDriver ICs, manufacturers can use the same platform across all applications – from 400Vac to 690Vac line – simplifying their design process. FluxLink technology supercedes commonly used but problematic optocouplers and SCALE technology ensures compact, robust and reliable designs that are simple and quick to create.”

1700V SCALE-iDriver ICs deliver a gate current of up to 8A and support systems of over 110kW without an external booster, or up to 30A gate current and over 400kW with an external booster. 1700V SCALE-iDriver ICs suit applications in industrial drives, power supplies/UPS, photovoltaic inverters of all sizes, industrial HVAC, EV charging and traction equipment including commercial EVs. SID1183K devices are available now priced at $3.19 in 10,000-piece quantities.
