US semiconductor supplier Microchip Technology has introduced a portfolio of IGBT 7 devices in different packages, multiple topologies and current and voltage ranges for power applications in More Electric Aircraft (MEA) as well as solar inverters and commercial and agricultural vehicles.
The lower on-state IGBT voltage (Vce), improved antiparallel diode (lower Vf) and increased current capability can enable lower power losses, higher power density and higher system efficiency, according to the company.
The lower-inductance packages, combined with the higher overload capability at Tvj −175° C, make the devices well-suited to rugged and high-reliability aviation and defense applications—such as propulsion, actuation and power distribution—at a lower system cost.
The IGBTs are available with voltages ranging from 1,200 V to 1,700 V and current ranging from 50 A to 900 A.
Designers can select a suitable power device based on their requirements. The devices are offered in standard D3 and D4 62 mm packages, as well as SP6C, SP1F and SP6LI packages.
Many configurations are available in the following topologies: three-level Neutral-Point Clamped (NPC), three-phase bridge, boost chopper, buck chopper, dual-common source, full-bridge, phase leg, single switch and T-type.
For motor control applications where enhanced controllability of dv/dt is important, the IGBT 7 devices are designed to offer freewheeling softness for efficient, smooth and optimized driving of switches. They also aim to improve system reliability, reduce EMI and minimize voltage spikes.
The variants of the IGBT 7 portfolio are available to purchase in production quantities.
“The IGBT 7 portfolio combines ease of use and cost efficiency with higher power density and reliability, offering our customers maximum flexibility. These products are designed for general industrial applications as well as specialized aerospace and defense applications,” said Leon Gross, Corporate VP of Microchip’s discrete product group. “Additionally, our power solutions can be integrated with Microchip’s broad range of FPGAs, microcontrollers (MCUs), microprocessors (MPUs), dsPiC Digital Signal Controllers (DSCs) and analog devices to provide a comprehensive system from one supplier.”
