2013 IEEE Energy Conversion Congress and Exposition, 2013
In this paper, a single-phase voltage-doubler with mismatched capacitors that converts a single-phase AC voltage to two balanced DC output voltages is proposed. It is based on a half-bridge rectifier and consists of two legs: one rectification leg to convert the AC voltage to DC output voltage and one neutral leg to split the DC output voltage into two

A Low Output Voltage Ripple Fully-Integrated Switched-Capacitor DC-DC Converter
2019 IEEE 62nd International Midwest Symposium on Circuits and Systems (MWSCAS), 2019A fully-integrated switched-capacitor (SC) DC-DC converter that steps down 3.3 V to 1.5 V with a peak efficiency of 68% is implemented in a 2P3M 0.6-µm CMOS process with a 555 pF poly-poly flying capacitor and a 1.34 nF MOS tank capacitor. This paper demonstrates a means of applying a low-frequency input clock as part of a time-interleaving technique ...

Modular Multilevel Converter Based Variable Speed Drive With Reduced Capacitor Ripple Voltage
IEEE Transactions on Industrial Electronics, 2019In recent years, modular multilevel converter (MMC) is considered for medium-voltage variable speed drives (VSD) due to its modularity and higher reliability. However, the major drawback of the MMC-based VSD is the higher capacitor ripple voltage at lower operating speeds.

2011 IEEE International Conference on Industrial Technology, 2011
A modulation method for capacitor voltage ripple reduction of the switched-capacitor inverter using series/parallel conversion (SCISPC) is proposed. The phase shifted pulse width modulation (PWM) method and the level shifted PWM method are applied to the proposed modulation method. The two capacitors in the 7-level SCISPC is charged alternately by this

Modular multilevel converter: theoretical analysis and capacitor voltage ripple effects
2012A theoretical analysis of the Modular Multilevel Converter is presented. The interaction between arm currents and modulating signals causes capacitors voltage oscillation at both fundamental frequency and twice the fundamental frequency. Capacitors voltage oscillation is the cause of undesired DC and second order harmonic voltage in the converter arms,
