Abstract
Switch cells consist of an array of power switches and passive components which can replace the main switches in many power topologies, allowing reduced switching loss without altering the power topology directly. The switch cell topology discussed herein utilizes a saturable resonant inductor to reduce the size and power loss of the cell. Additionally, the cell transfers energy stored in the inductor into a capacitor for efficient energy storage during the cell's conduction region. This energy is then transferred back to the system when the cell turns off, thus reducing the total switching energy.
