1-STEP AC-DC Power Conversion

Unparalleled Power Density

Our patented 1-STEP technology is revolutionizing power conversion with an innovative circuit solution that uniquely achieves 3-phase active power factor correction, power regulation and electrical isolation in a single conversion step .   

Engineered to deliver improved conversion efficiency and power density in a simplified topology, 1-STEP ac-dc converter solution reduces weight, size, cost, complexity and risk for mission-critical applications. 

1-STEP can be scaled up in parallel to meet any output need such as those required by high-power systems found in next-generation military and commercial aerospace platforms .
