  • A High-Efficiency Resonant Switched Capacitor Converter With Continuous Conversion Ratio
    IEEE Transactions on Power Electronics, 2015
    Co-Authors: Alon Cervera, Michael Evzelman, Mor Mordechai Peretz, Shmuel Ben-yaakov
    Abstract:

    A resonant switched capacitor converter with high efficiency over a wide and continuous Conversion Ratio range is introduced. The efficiency of the topology depends primarily on the conduction losses and is decoupled, to a large extent, from the voltage Conversion Ratio. This is an advantage over classical switched capacitor converters, for which the efficiency is strongly related to the Conversion Ratio. The opeRation principle applies three zero current switching states to charge, discharge, and balance the remaining charge of the flying capacitor. This results in a gyrator, i.e., a voltage-dependent current source, with a wide range of voltage Conversion Ratios (smaller as well as greater than unity) as well as bidirectional power flow capabilities. The analytical expressions for the Conversion Ratio and expected efficiency are provided and validated through simulations and experiments. The experimental verifications of the converter demonstrate peak efficiency of 96% and above 90% efficiency over a wide range of voltage gains and loading conditions. In addition, the system was found to be highly efficient at the extreme cases of both light and heavy loads.

The efficiency of the topology depends primarily on the conduction losses and is decoupled, to a large extent, from the voltage Conversion Ratio. This is an advantage over classical switched capacitor converters in which the efficiency is strongly related to the Conversion Ratio. The opeRation principle applies three zero current switching (ZCS) states to charge, discharge and balance the remaining charge of the flying capacitor. This results in a Gyrator-behaved voltage-dependent current source with a wide voltage Conversion Ratio (smaller as well as greater than unity) as well as bidirectional power flow capabilities. The analytical expressions for Conversion Ratio and expected efficiency are provided and validated by simulation and experiments. The experimental verification of the converter demonstrates peak efficiency of 96%, and above 90% efficiency over a wide range of voltage gains and loading conditions.

  • design of single topology continuously scalable Conversion Ratio switched capacitor dc dc converters
    IEEE Journal of Solid-state Circuits, 2019
    Co-Authors: Nicolas Butzen, Michiel Steyaert
    Abstract:

    This paper introduces a fundamentally different type of switched-capacitor dc–dc converter with large voltage swing flying capacitors, which is made efficient using advanced multiphasing soft charging. A single-capacitor topology is derived that behaves like a gyrator and achieves a continuously scalable-Conversion-Ratio with high efficiency. A circuit fabricated in a 28-nm CMOS process demonstrates the working principle of the presented topology and advances the state of the art by achieving a peak efficiency of 93%, and a single-topology 0.9–2.03-V output voltage range with more than 90% efficiency at an input voltage of 2 V.
