RockeTruck, Inc. Unveils New “PowerGate 1500”
Medium Voltage Converter Stack at AIx Energy Summit
March 19, 2026 – RockeTruck, Inc., a developer and manufacturer of advanced power generation and conversion products, today unveiled its latest advanced power converter component, the “PowerGate 1500” at the AIx Energy Summit in San Diego.
The PowerGate 1500 integrates an H-Bridge power printed circuit board, gate driver, DC-to-DC converter, and current and voltage sensors into a compact medium voltage converter stack. It was designed primarily for use in solid-state transformers (SSTs), which are being developed by numerous companies to support medium voltage direct current (MVDC) power distribution in future data centers and other facilities with heavy DC power loads.
Three identical PowerGate 1500 units can be integrated with an isolating transformer and data cards (also developed by RockeTruck) into a medium voltage converter module, 24 of which can convert AC power from a typical grid connection to 1,500-volt DC power. Hence a total of 72 PowerGate 1500s can form the backbone of an SST, which maximizes parts commonality while minimizing manufacturing and maintenance costs. “The PowerGate 1500 can be a key building block for the SSTs urgently needed to meet future grid power demands,” according to Mike Simon, RockeTruck’s President & CEO.
The PowerGate 1500 is the first major new SST component developed by RockeTruck under its “Electric Vehicle Direct Current Hub” (EVDCH) project, funded with a $4 million grant received from the California Energy Commission (CEC) in late 2024. The PowerGate 1500 uses advanced silicon carbide (SiC) transistors to deliver high quality power in an exceptionally small package. Under the EVDCH project, an SST using the PowerGate 1500 will be used to distribute DC power at a public electric vehicle charging facility at the Port of Long Beach in California starting in 2027, demonstrating another promising application for SSTs. In addition, RockeTruck is developing a PowerGate 800 to support DC distribution at 800 volts.
RockeTruck, a privately held company founded in 2020, also develops and manufactures advanced power conversion devices using gallium nitride (GaN), which can be used to reduce the voltage of power distributed at 800 to 1,500 volts to the lower levels required in data server racks, typically 12 to 48 volts. RockeTruck also builds integrated power generator systems using hydrogen fuel cells and batteries, including a new “Mobile Fuel Cell Generator” that can supply clean power for outdoor television and movie studios, concerts and sporting events, and other off-grid activities requiring large amounts of power.
