Optimization Methods to Reduce Capacitor Stress in Modular Multilevel Converters
IEEE Access, 2020 Modular multilevel converters consist of many capacitor half-bridge or full-bridge converter cells. Stresses on the capacitors result from peak capacitor voltage, capacitor voltage ripple and current ripple.

Techniques to Reduce Capacitor Voltage Ripples in Multilevel Inverters
IEEE Access, 2023 Reducing ripples on the capacitor voltage has two benefits: improved output waveform quality and accurate converter size. During the generation of a given output voltage level, the factor “Inherent Redundant Paths (IRPs)” has a considerable impact on the characteristics of multilevel inverter design.

Reduction of Ripple Voltage in a Dynamitron [PDF]
IEEE Transactions on Nuclear Science, 1983 We determined that a precise neutralization of the RF ripple voltage on the high voltage terminal of a Dynamitron has previously been prevented by a nonnegligible phase shift of RF currents in the two halves of the ~l00 kHz class C oscillator tank circuit, which is actually constituted of two slightly unequal high-Q coupled circuits because it has two ...

Considerations on Voltage Ripple Assessment in dc Power Network
2022 IEEE 12th International Workshop on Applied Measurements for Power Systems (AMPS), 2022 The main components used for integration in the power system of distributed renewable energy sources, basically work in dc, f.i. batteries, photovoltaic systems and fuel cells. In addition, most common loads already use dc power internally, usually provided by rectifiers.

Methods for Ripple Index evaluation in DC Low Voltage Distribution Networks
, 2007 International audiencePower Quality indices for ripple evaluation in DC Low Voltage networks are presented and discussed. Ripple is interpreted in a more general way than a simple periodic fluctuation of network voltage due to rectifying harmonics: the ...

Analysis and Control of Current Ripples of Z-Source Inverters
IEEE Access, 2020 Load current ripple is an important issue in the design and control of inverters since it influences the torque ripple and noise amplitude of a motor drive. The current ripple of Z-source inverter (ZSI) is analyzed in this paper.
