Miniaturized high performance power converters can benefit power electronics enabled applications by reducing system volume and cost, improving efficiency, and enhancing system functionality and performance. Architectural innovation enables miniaturization and performance improvements. An emerging trend is to use more sophisticated and distributed circuits and controls to leverage the advances of active semiconductor switches over passive components and realize efficient power conversion with reduced device stress and energy storage requirements. In this webinar, I will present a hybrid switched capacitor magnetics power conversion architecture that can significantly reduce the passive component size in power converters, and at the same time realize high power density, high efficiency, and low cooling requirements. A systematic approach to modeling impedances and current distribution in planar magnetics will also be presented. This approach opens fertile ground for magnetic component optimization and architectural innovation through more sophisticated magnetic design. Finally, I will discuss how architectural innovations in power electronics can benefit efficiency and performance in many power processing and energy management systems, ranging across solar micro-inverters, telecommunication power supplies, and LED drivers.
