摘要：
This paper presents the analysis and design of a non-isolated, current-fed buck-boost DC-DC converter. The converter is capable of performing both buck and boost operations with zero-ripple input current. An active-clamp circuit is used to recycle the energy stored in the leakage inductance, which minimizes the voltage stress of main switch and provides zero-voltage switching at turn-on. The circuit configuration, operation principle and design considerations of the converter in boost mode are discussed in detail. Experimental results for a 300 W hardware prototype with an input voltage range of 40-50 V and regulated output voltage of 400 V are obtained for validation of the converter topology.
