New technology enables electric buses and other e-transportation power systems to meet and exceed stringent environmental conditions while maximizing efficiency.
To complement its broad portfolio of silicon carbide MOSFET discrete and module products, Microchip recently announced a new 1200V production-ready digital gate driver, providing system developers with multiple levels of control and protection for safe, reliable operation and qualified to stringent transportation requirements.
For designers of silicon carbide-based power conversion equipment, Microchip’s AgileSwitch® 2ASC-12A2HP 1200V dual-channel digital gate driver with its Augmented Switching™ technology is production-qualified and fully configurable. To ensure reliable, safe operation, the 2ASC-12A2HP gate driver provides multiple levels of control and a higher level of protection for silicon carbide MOSFET-based power systems. When compared to conventional gate drivers, key performance attributes of the AgileSwitch gate driver products include the ability to dampen drain-source voltage (Vds) overshoots by up to 80% and slash switching losses by as much as 50%. The 2ASC-12A2HP digital gate driver can source/sink up to 10A of peak current and includes an isolated DC/DC converter with low capacitance isolation barrier for pulse width modulation signals and fault feedback.
This new tool enables designers to adjust system performance through software upgrades using the AgileSwitch® Intelligent Configuration Tool (ICT) and a Device Programmer. No soldering required.
The Microchip HPFM-00117 is a single-channel, plug-and-play gate driver board for 1.2-3.3kV high-power modules such as IHV, IHM, HiPAK™ and others.
