초록
This paper discusses the ZVS/ ZVZCS Three-Level converter using the minimum auxiliary circuit. A primary auxiliary circuit, which consists of one coupled inductor is added in the primary circuit to provide ZVZCS conditions to primary switches. ZVS is for outer switches and ZCS or ZVS is for inner switches. Many advantages including simple circuit topology high efficiency, and low cost make this converter attractive for high power applications. The principle of operation, feature and design considerations arc illustrated and verified through the experiment with a 2kHz 400kHz IGBT based experimental circuit.
