摘要：
Bidirectional converters are increasingly being used in electric vehicle chargers and self-consumption for residential/communities with energy-storage capabilities. Among existing bidirectional solutions, bridgeless totem-pole arrangement has been of great interest to both academia and industry due to its advantages of enabling ultra-high efficiency, i. e. above 99%, at low complexity. However, until now most research and development have mainly focused on AC/DC power factor correction (PFC) applications of the bridgeless totem-pole topology with very little effort to understand the practicality and performance of the converter in generation mode, i.e. DC/AC power inversion. Therefore, this article discusses the feasibility of the 3-level bridgeless totem-pole arrangement used as a DC/AC inverter in either islanded or grid-tied operation. This work is experimentally validated by a 3kW bidirectional PFC/Inverter prototype in a compact format of 41mm x 302mm x 1U with peak efficiency exceeding 99% at 230V for all operating modes.
