Abstract
A power converter with a modular, compact architecture with a reduced component count is disclosed. The power converter includes parallel power conversion sections and utilizes one or more mutual coupling input inductors with multiple windings. The windings are connected in pairs in a differential mode between a power source and the parallel power conversion sections. Each power conversion section receives the same input voltage and generates the same output voltage. As a result of the winding connections and the same input and output voltages, the input of the power converter exhibits current balancing and sharing between each branch of the parallel configuration, allowing a single current sensor to provide a measurement of the current and a single controller to control operation of each of the power conversion sections.
