| Abstract |
A new buck-and-boost (i.e., step-up/down) dc-dc converter is introduced and practically evaluated.
This converter consists of two self-turn-off switches, two FRDs and a small dc-inductor, and it
performs boost, buck and even buck-boost dc-dc converter operations. Applying the boost and buck
operations, this new converter obtains a seamless and wide-range output voltage control from buck
region to boost region. The advantage of the new converter in efficiency for the dual-switch cascade
converter in Buck region is analyzed and practically confirmed. |
