Voltage Ripple Reduction in Voltage Loop of Voltage Source Converter
International Journal of Power Electronics and Drive Systems (IJPEDS), 2017 In order to achieve a good dynamical response of a full-bridge AC-DC voltage source converters (VSC). The bandwidth of PI controller must be relatively wide. This leads to the voltage ripple produced in the control signal, as known that its ripple frequency has twice of the line frequency and cause the 3rd harmonic of an input current. A Ripple Voltage

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.

A compensation method of ripple voltage on DC tacho-generator.
IEEJ Transactions on Industry Applications, 1990 AbstractA dc tachogenerator has been used widely in such applications as computer peripherals and machine tools. However, this generator has some problems, e.g., the ripple voltage involved in the output voltage and the abrasion of the brush and the commutator.
