Technical Papers
1-Step AC-DC Conversion White Paper

Discover three-phase power conversion in a single step with 1-STEP, Marotta’s patent-pending power conversion technology. 1-STEP offers active power factor correction and isolated, regulated, DC output with unparalleled power density. 

Electronically Controlled, Piezo-Actuated, 10K Regulator

Marotta has developed an electronically-controlled pressure regulator suitable for spaceflight, defense, and facility applications. Through a closed loop electronic control system controlling piezo-actuated pilot valves, the regulator constantly measures actual downstream outlet pressure and adjusts to changing inlet conditions, resulting in an accurate outlet pressure insensitive to inlet pressure, flow rate, and temperature. 

 Regulator for Xenon Feed System

This paper presents the development of a single-stage, cold-redundant, standalone electronic pressure regulation system which throttles xenon propellant flow using a normally-closed magnetostrictively-actuated proportional control valve operated with a dedicated electronic control unit.
