AC vs. DC Boost Converters: A Detailed Conduction Loss Comparison [PDF]
, 2019 Studies have shown the efficiency benefits of DC dis- tribution systems are largely due to the superior performance of DC/DC converters. Nonetheless, these studies are often based on product data that differs widely in manufacturer and operating voltage.
