Modelling and prediction of current harmonics generated by power converters in distribution networks
IET Generation, Transmission and Distribution, 2021 Predicting current harmonics in distribution networks is essential to find harmonic losses and power quality indices. In order to predict the current harmonics, the effect of grid impedance and voltage distortions on grid‐connected power converters need ...

Interleaved Pulse Width Modulation Based on Modified Carrier in Parallel Operation
IEEE Access, 2021 An interleaved pulse width modulation (PWM) can be employed in a parallel operation of three-phase converters because the interleaved PWM increases the equivalent switching frequency and significantly enhances the output current harmonics.
