Isolated, Regulated DC Output in One Conversion Reduces Cost, Complexity and Risk
Executive Summary:

Military and industrial OEMs seek continuous improvements in power conversion in the extreme environments found in military, shipboard and aviation electronics. Multi-step regulation and isolation of electronic circuits is a complex and costly process that is commonly required for AC to DC conversion in high power applications, demanding close attention to performance requirements such as power factor and current distortion, as well as size, weight, efficiency and cost.

To solve these challenges for the power conversion engineer, Marotta Controls has developed its new patent-pending 1-STEP AC-DC Conversion, an innovative new circuit solution that uniquely achieves three phase active power factor correction (APFC), power regulation and electrical isolation in a single conversion step. Marotta’s new design ensures the highest power and efficiency while reducing costs. This report provides a brief technical overview of 1-STEP AC-DC Conversion, contrasting this new technology to existing conversion options such as auto transformer rectifier units (ATRUs) and Vienna rectifiers, offering quantified test results, and highlighting competitive value and ideal applications.
