New Demands for Power Require New Power Electronics Solutions
These are some of the electrification applications that can benefit from wide bandgap power converters and transformers
Data Centers & EV Charging
AI data centers and EV charging facilities are placing unprecedented demands on the electric power grid. Rewiring such facilities for direct current (DC) power distribution can mitigate these demands, while also enabling use of new megawatt-class DC-powered server racks and fast chargers. This will require new generations of converters powered by WBG semiconductors, ranging from multi-megawatt solid-state transformers to tiny DC-to-DC converters.

Transportation & Mobility
Electrification of transportation systems, particularly commercial trucks, trains, and marine vessels, is being accelerated by environmental concerns, rising oil prices, and advances in battery technology. This is driving demand for inverters and DC-to-DC converters that are smaller, lighter, more efficient, and capable of operating at higher voltages. WBG semiconductors can surpass silicon performance in all of these areas.

Aerospace & Defense
Air and space vehicles have particularly urgent needs for smaller, lighter power conversion devices, including product that can operate in high temperatures and harsh radiation environments. New high-energy weapon systems such as lasers, railguns, and microwave weapons required fast switching and higher voltage operation. WBG semiconductors are desirable if not essential to meeting all of these requirements.

Grid Modernization
The electric power grid must be upgraded to integrate distributed energy resources (DERs) such as wind power, solar power, and battery energy storage, and to utilize new architectures such as microgrids and virtual power plants. These changes are driving demand for more capable and efficient power converters and transformers to convert DC power from DERs to the AC power used by the grid and most grid-connected facilities, and to recharge batteries by converting grid AC power back to DC.

MVDC Distribution for EV Charging
Bandgap Technologies is developing a solid-state transformer (SST) and Medium Voltage Direct Current (MVDC) power distribution architecture to be installed at the Zeem Solutions electric truck charging facility in Long Beach, California in 2027. The SST will convert AC power from the grid to 1,500-volt DC power, which will be routed to a new set of EV chargers that will convert this power to the DC voltage required to recharge truck batteries (600-800 VDC). Converting the grid AC power to DC within the SST, as opposed to doing this within every EV charger, will simplify the design of the EV chargers while improving overall power distribution efficiency. The SST will use a “Cascade H-Bridge” (CHB) architecture using the latest silicon-carbide (SiC) semiconductor devices and a modular design approach built around Bandgap Technologies’ novel PowerGate Bridge. The SST and DC distribution architecture developed under this “Electric Vehicle Direct Current Hub” (EVDCH) demonstration project, funded by the California Energy Commission and the Ports of Los Angeles and Long Beach, can also be used in new data centers to improve electrical efficiency and simplify the design of the next generation of data servers.
Mobile Fuel Cell Generator
A Mobile Fuel Cell Generator (MFCG) recently developed by Bandgap Technologies is presently serving as a mobile testbed for one of the world’s most powerful gallium nitride (GaN) inverters, which converts DC power from a fuel cell and battery pack to AC power that can be exported to various facilities and devices. The compact design of this 120-kilowatt generator – which can fit in the bed of a standard pickup truck – is made possible in part by the inverter size reductions enabled by GaN semiconductors, which have greater electron mobility and operate at higher switching frequencies than silicon or SiC-based devices. These features enable GaN inverters to be built with smaller heat sinks and filter components, making them an ideal choice for applications that require the smallest, lightest possible power conversion devices
