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
