Improved Operation of the Step-Up Converter with Large Voltage Gain and Low Voltage on Capacitors
This work proposes an improvement for a recently proposed converter. The discussed converter is the so-called low-voltage in capacitors (LVC). It offers a larger voltage gain compared to the standard step-up or boost converter while operating with a ...

A plug-and-play ripple mitigation approach for DC-links in hybrid systems [PDF]
© 2016 IEEE.In this paper, a plug-and-play ripple mitigation technique is proposed. It requires only the sensing of the DC-link voltage and can operate fully independently to remove the low-frequency voltage ripple. The proposed technique is nonintrusive

Implications of Pulser Voltage Ripple [PDF]
In a recent set of measurements obtained by G. Kamin, W. Manning, A. Molvik, and J. Sullivan, the voltage waveform of the diode pulser had a ripple of approximately {+-} 1.3% of the 65 kV flattop voltage, and the beam current had a larger corresponding ripple of approximately {+-} 8.4% of the 1.5 mA average current at the location of the second Faraday

Evaluation of DC-Link Voltage Switching Ripple in Multiphase PWM Voltage Source Inverters [PDF]
This paper presents a generalized approach towards the dc-link voltage switching ripple analysis in two-level multiphase PWM voltage source inverters with balanced load. Since voltage ripple is one of the crucial sizing criteria for dc-link capacitor, simple and practical equation for designing the dc-link capacitor, based on the maximum (peak-to-peak)
