Voltage-distortion of current-controlled converters with DC ripple

In controlled power converters, the operating point is determined by the DC current mean value, which in the case of a DC ripple considered by the authors makes the precalculation of the main voltage disturbances somewhat difficult. Fundamental investigations in the time domain show the different effects of commutation and ripple. Based on an analytical description, the authors show that the time behaviour of the voltage disturbance can be derived piecewisely in an easy way
