OUR STORY

WBGlobalSemi, Inc. (WBGS) was founded to commercialize a new class of high power wide band gap (WBG) silicon carbide (SiC) bi‐polar junction transistors (BJTs) and power modules for use in high power industrial applications such as aerospace, main grid, micro-grid, traction and military.

​

Our eight person founding team has over 240 years combined experience in the commercialization of technology and over 160 years combined experience in commercial power electronics.

OUR VISION

We are addressing a large high power module market today, with high growth predicted by industry analysts from $3 billion annual revenue in 2018 projected to grow to $4 billion by 2022. This market is dominated by legacy Si-based and some new SiC-based Insulated Gate Bipolar Transistors (IGBTs) used to deliver high power.

​

SiC BJTs have not been adopted by the WBG power module design community to date, which designs either IGBTs or in some cases MOSFETS into target applications with appropriate drivers. Until recently three fundamental development challenges prevented the adoption of conductivity modulated WBG power semiconductors - materials quality, manufacturing capability, and drivers.

​

Our team has deep circuits, devices, and driver knowledge, as well as proven 15 kV SiC BJT lab prototyping success. We know these challenges can now be overcome. Our goal is to commercialize high power BJTs, initially from 45 kW to 600 kW. Our BJTs will deliver high voltage or high current or both, depending on customer requirements. We design-to-customer to achieve initial design wins and to build our product line.

PRODUCT STRATEGY

We are designing-for-customer and in particular large corporations to assure rapid acceptance and qualification of our products. Our current focus is on (a) a 6.5 kV, 50 Amp BJT power module and (b) a 200 V, 3,000 Amp pulsed power module BJT family.

These can be manufactured today using the best materials and with tight control over the manufacturing process.  Our team has developed optimized driving circuits for various power applications and we are confident we can deliver optimal BJT performance.
