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-to-dc power converter solution reduces weight, size, cost, complexity and risk for mission-critical applications. 

When compared to traditional 3-phase AC-to-DC converters, this represents a huge step forward in efficiency and performance. The innovative design of these solutions allows them to achieve conversion in a single component compared to three which are requirements in conventional methods. First and foremost, this means our units are more efficient and offer higher power power density. 1-Step is designed to work  in today’s more challenging military and commercial avionic applications, delivering greater output and contributing less weight.

The qualities these modules offer makes them ideal for use in demanding environments such as those encountered by heavy-lift military aircraft.

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.  To learn more about any of these solutions, download their datasheets.
