具有容错能力的双开关降压型DC/DC变换器的推导

This letter presents a graph-theoretic approach to deriving a family of dual-switch step-down dc/dc converters with fault-tolerant capability. The constraint sets in the derivation process ensure that minimum additional component is used to achieve fault-tolerant operation. The operation of converters derived is flexible. Under normal operating conditions, one of the two switches can serve as a ma...
