摘要: Multilevel switched-capacitor DC-DC converters have been proposed for applications that require interfacing two DC-buses or sources. High-voltage DC-bus in general is specified to be an integer multiple of the low-voltage side. Low efficiency, bulky capacitor banks and unequal voltage sharing identified as some shortcomings these converter topologies. This paper will show how overcome above mentioned even when relatively small are employed. It shown connecting a very inductor (parasitic cable inductance adequate) series with clamping capacitors leads significant improvements performance. For given performance, size can greatly reduced L r included. makes it possible build more compact efficient converters.
