One core stage, three power classes.

Because a PPU is a full space-power-electronics programme hiding inside "a thruster". Building one in-house diverts a plasma team into converter design, EMI and qualification for years. A merchant unit turns that into an interface-control document and a test campaign.

Because a PPU's mass lives mostly in its electromagnetics, and their size falls with switching frequency. Wide-bandgap GaN devices switch fast enough to shrink them — the route to a substantially lighter unit per kW. Our engineering model is designed around GaN FET candidates with published radiation data, derated and screened for space-relevant risks; the silicon ZVZCS breadboard remains the qualification anchor while that design matures. The field analysis is on the landscape page.

Because that is where the supply gap and the customers meet: no merchant EP power supplier exists in India today, domestic demand is compounding, and proximity matters in a hardware integration business. We are a private company; the heritage is our team's, not an affiliation.

Export-control-aware by design: Indian design authority and a non-US-origin architecture reduce licensing friction for many buyers, but specific transactions always require their own review. We do not market legal conclusions.

Through the planned sequence on the technology page — bench sweeps, thermal-vac and EMI on the engineering model, arc and ignition campaigns against a simulator, then a thruster-coupled vacuum firing. Gates published as they are passed.
