摘要：
Two stage ac-dc converters consisting of front-end power factor correction ac-dc boost converter followed by an isolated dc-dc converter form the industry workhorses for powering network servers, telecom, and other dc loads. For safe and uninterrupted operation during sudden intermittences in power supplied from the ac mains, the ac-dc power converter should be able to supply the load with constant dc output voltage in order to prevent them from unwanted resetting or in other words exhibit sufficient hold-up time (HUT) operation. This paper proposes a novel dc-dc nonresonant full-bridge converter with extended HUT capability and reduced dc-link storage capacitance.
