Active-Clamp Resonant Power Factor Correction Converter With Output Ripple Suppression
An active-clamp resonant power factor correction converter with output ripple suppression is proposed and analyzed. It combines a buck power factor correction (PFC) unit and a resonant dc-dc unit by sharing one active switch.

A CMOS Ripple Detector for Voltage Regulator Testing [PDF]
This paper presents an RMS based ripple sensor for testing of fully integrated voltage regulators. A DC signal which is proportional to the input ripple amplitude is generated. Final digital pass/fail signal is obtained with a clocked comparator. The sensor can detect a peak-to-peak ripple voltage of up to 50 millivolts on the 1.2 V supply rail and has

A new DC-APF control strategy for DC microgrid
The ripple component of the DC bus voltage will affect the power supply quality of the entire DC microgrid and the safety of equipment operation. Therefore, a new DC active power filter (DC-APF) control strategy was proposed to suppress the DC bus ...

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 ...

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

Techniques to Reduce Capacitor Voltage Ripples in Multilevel Inverters
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.

Optimization Methods to Reduce Capacitor Stress in Modular Multilevel Converters
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.

Considerations on Voltage Ripple Assessment in dc Power Network
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.

Pareto Frontier of the Arm Energy Ripple and the Conduction Losses of a Modular Multilevel Converter
Modular multilevel converters can achieve high power quality and voltage ratings, becoming a good alternative for high-voltage direct-current applications. However, the circulating current and capacitor voltage ripple remain significant drawbacks, mainly

Reduction of Ripple Voltage in a Dynamitron [PDF]
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 ...
