A Design Methodology for Switched-Capacitor DC-DC Converters

Abstract : This paper proposed a new high-voltage gain resonant switched-capacitor dc-dc converter for high-power offshore wind energy systems. The proposed new dc-dc converter is characterized by the resonant switching transitions to achieve minimal switching losses and maximum system effi ciency. Here, the converter operates at fi fteen times as high as the input voltage with a small device c...

An improved modulation strategy based on minimum energy storage for DC-link capacitance reduction in a six-switch AC-AC converter is proposed. The proposed enables the capacitor to accumulate and release twice each complete switching cycle, achieving effect of “fast charging discharging”. Meanwhile, inversion rectification are modulated synchronously. Hence, there stored capacitor. Then, time a...

This article presents a stability enhancement control scheme applied in the three-phase back-to-back (BTB) converters with L filter. The is concocted using feedback of DC-link capacitor current without additional sensors. Both grid-side are equipped this scheme, which can also be called coordinated compensation scheme. In article, DC terminal impedance models two before and after optimization c...
