Maximizing performance of power electronics by minimizing magnetic energy storage
Magnetic components' cost, size and loss inhibit progress in power electronics. The required size is largely driven by the energy storage required, and co-design of circuits and magnetics to minimize energy storage can result in small and efficient converters. Examples presented will include magnetics for high-current-density low voltage power delivery at >4 A/mm2, and new circuits to replace 60 Hz transformers, including in V2H bidirectional EV charging.
