New AgileSwitch SiC gate driver optimised for 62mm modules

To support the rapid migration of high-power industrial systems from IGBTs to silicon carbide (SiC) devices, AgileSwitch has announced a series of plug-and-play SiC MOSFET gate drivers for 62mm modules. Typical applications include heavy-duty traction vehicles, auxiliary power units in trains and induction heating systems. The patented Augmented Turn-Off™ switching technique, high noise-immunity design and the advanced monitoring/fault reporting facilitate conversion from IGBTs to 62mm SiC MOSFET power modules.

Designers want high speed switching using smaller, lighter, less expensive system components

“Designers want the benefits of switching at higher speeds using smaller, lighter, less expensive system components,” says Rob Weber, CEO of AgileSwitch. “Typically, this can only be achieved by reducing the switching efficiency, which effectively negates much of the benefit. The 62EM series enables higher switching frequencies and high efficiency by dramatically reducing the secondary effects of high switching frequency: voltage overshoots, ringing and false short circuit reporting.”

Safe operation at higher frequencies

By reducing turn-off spikes and ringing, SiC MOSFET modules can be safely operated at the higher frequencies that enable dramatic increases in power conversion density. This allows SiC MOSFET modules to be operated closer to their rated specifications, resulting in size, cost and performance improvements.

Designed for harsh environments

The 62EM gate driver is designed for harsh, high-noise environments. It is equipped with powerful diagnostic and troubleshooting tools and it continuously monitors critical parameters such as temperature and DC link voltage. A white paper describing the performance improvements achieved using ATOff is available.
