Our Mission

RockeTruck’s mission is to deliver inverters, DC-to-DC converters, and solid-state transformers using wide bandgap semiconductors to support new electricity uses and distributed power generation options that demand more power, higher voltage, and improved safety and reliability.

Our Approach

The foundation of RockeTruck’s vertically integrated approach is to develop power modules and inverter stacks using wide bandgap semiconductors (silicon carbide and gallium nitride) to achieve unprecedented performance.  These products can then be purchased as components; incorporated into high-power inverters, DC-to-DC converters, and solid-state transformers; or used as key elements of end-to-end system architectures featuring advanced generators and/or power distribution methods.
