MOSFET

Silicon Carbide (SiC) MOSFETs fabricated on n-type Silicon Carbide enable higher switching frequencies reduce component sizes of inductors, capacitors, filters & transformers. SiC MOSFETs replace silicon devices with higher blocking voltage, and lower switching and conduction losses.

HEMT

HEMTs fabricated on GaN epitaxial layers and HPSI Silicon Carbide substrates enable performance far exceeding that of any other technology, for any application with world-beating bandwidth, efficiency and frequency of operation.

Diode

Unipolar Schottky diodes fabricated on Silicon Carbide substrates can be used at voltages where Si is restricted to bipolar devices. These unipolar devices have lower switching losses, resulting in more efficient power conversion systems than are capable with silicon diodes.

Silicon Carbide Meets Power V2G Demands in EV Fast-Charger Market

This paper explores how silicon carbide (SiC) technology continues to be a leading solution for power and vehicle-to-grid (V2G) demands in the fast growing fast-charger market. V2G is gradually developing as companies innovate compelling business models for powerful energy storage systems (ESS) on wheels. While solar power and stationary ESS will certainly have an important place in the electrified future, V2G is being looked at for dealing with load peaks.
