Marel Power Solutions Builds the Stack Behind Electrification

Marel Power Solutions is a Plymouth, Michigan power-electronics company building modular power modules and power stacks for electric mobility, defense systems, and data centers. Founded in 2019, Marel sits between semiconductor suppliers and system builders, where electrical design, thermal management, packaging, and manufacturing all have to work as one system.

CEO Amrit Vivekanand leads the company alongside Chief Technology Officer Ian Byers and Chief Operating Officer Gary Miller. Marel’s current opportunity is bigger than making one compact inverter. It is trying to turn power conversion into a configurable platform that can travel across applications without forcing every customer to start with another bespoke design.

That thesis matters now because electrification is pushing more power through less space. Electric vehicles, defense platforms, charging systems, and AI data centers face different operating environments, but they share the same unforgiving math: heat, weight, volume, semiconductor supply, reliability, and cost all show up in the same box.

About Marel Power Solutions

Marel Power Solutions builds the modules and stacks at the center of high-power converters, inverters, breakers, chargers, and propulsion systems. Its power module is the core semiconductor package. Its power stack combines those modules with cooling, bus structures, controls, and related components to create a configurable conversion block.

The company says its architecture can cut size and weight, reduce semiconductor count, and simplify system design by integrating thermal and electrical paths more tightly. Marel currently supports silicon and silicon-carbide devices and describes gallium nitride as a future option. It also offers its technology as products or through IP licensing.

Those claims need the usual hardtech discipline. Marel’s public materials use different comparison baselines, and the performance figures are company-reported rather than independently audited. The underlying engineering is still tangible. The company’s power module uses dual-side cooling and a low-inductance package, while its power stack is designed to replace application-specific converter assemblies with a reusable platform.

Why the Power Stack Is the Product

Power electronics are often discussed through semiconductor materials such as silicon carbide or gallium nitride. The die matters, but a faster switch still has to shed heat, connect to the rest of the system, survive vibration, and be manufactured at a price customers will accept. Packaging and cooling decide how much of the semiconductor’s theoretical performance reaches the real machine.

Marel’s strategic bet is that system builders should be able to configure the conversion layer instead of engineering it from scratch for each vehicle, aircraft, field system, charger, or rack. A repeatable platform could shorten development cycles, reduce engineering duplication, and make suppliers less dependent on one semiconductor vendor.

The company has patent support for that architecture. Byers and Miller are named inventors on Marel’s granted air-cooled power-converter patent. A Department of Energy project report also documents Marel’s work on manufacturing improvements for heavy-duty fuel-cell vehicle power electronics.

Three Markets, One Constraint

Mobility is Marel’s clearest near-term manufacturing lane. Smaller and lighter traction inverters, onboard chargers, and charging systems can return space and weight to the vehicle. A configurable stack could also let engineering teams reuse more of the same architecture across power levels and programs.

Defense systems place similar demands inside harsher operating conditions. Ground vehicles, aircraft, naval platforms, and deployable systems all need high current without letting wiring, cooling, armor, or enclosure weight consume the platform. Marel identifies defense as a target market, although no named defense deployment was independently verified.

Data centers create the newest version of the problem. Higher rack power and interest in 800V DC distribution increase the value of compact, efficient conversion between utility feeds, high-voltage buses, and lower-voltage rails. Marel positions its modular stacks for that transition, but named production customers in data centers were not publicly confirmed.

From Patent to Pilot Line

Marel’s most important current milestone is manufacturing. In September 2026, the company disclosed a $1.9M Michigan Supplier Conversion Grant to buy equipment for a pilot production line in Plymouth, beginning with electric-vehicle applications. Michigan selected Marel as one of 11 suppliers sharing $21M through a program supported by the U.S. Department of Energy.

The grant does not prove commercial scale. It funds the test that comes before it. A pilot line has to turn engineering into tooling, repeatable assembly, supplier controls, inspection, test procedures, cycle times, and customer qualification. In hardtech, that middle stage is where a polished prototype meets the less glamorous question that decides the business: can the company make the same thing twice, then a hundred times, without losing the advantage?

Public records also show earlier federal manufacturing work and a 2023 Michigan convertible note. Those different forms of support should not be rolled into a fictional total-funding number. What they do show is a multi-year effort to move Marel’s architecture from technical development toward production.

Leadership and the Next Operating Test

Vivekanand’s job now is to translate the technical platform into a repeatable commercial system. Byers brings the engineering and patent depth, while Miller’s operations role becomes more important as the pilot line takes shape. Marel’s official site also identifies leaders across customer programs, manufacturing, and sales and marketing.

The company’s public LinkedIn profile places the team in the 11-to-50 employee range and shows recent engineering interns. That is a useful talent-development signal, but it is not evidence of broad current hiring. Marel’s official careers page was password-protected at the time of research, and no open roles were independently verified.

The next proof points are operational: pilot-line capacity, customer qualification, production economics, independently validated performance, and evidence that one configurable stack can move efficiently across mobility, defense, and data-center programs.

Marel has a credible technical thesis and a newly funded manufacturing test. If the Plymouth line can turn compact power conversion into repeatable output, the company will have done more than shrink an inverter. It will have shown that one of electrification’s most customized layers can begin behaving like a platform.
