Harmonic assessment‐based adjusted current total harmonic distortion
The Journal of Engineering, 2016 Power systems suffer from harmonic distortion and extra ohmic losses associated with them. Moreover, all harmonic frequencies are mostly assumed to have the same effect on the system losses. However, the frequency‐dependency of the resistances should be taken into account, so that the apparent power and the power factor have to ...

Analysis and mitigation of dead time harmonics in the single-phase full-bridge PWM converters with repetitive controllers [PDF]
, 2018 In order to prevent the power switching devices (e.g., the Insulated-Gate-Bipolar-Transistor, IGBT) from shoot through in voltage source converters during a switching period, the dead time is added either in the hardware driver circuits of the IGBTs or ...

Bivariate stochastic model of current harmonic analysis in the low voltage distribution grid [PDF]
Proceedings of the Estonian Academy of Sciences, 2021 This paper presents a bottom-up bivariate analysis approach to estimate current harmonics by taking account of network and load variations. The current harmonics assessment in the presence of existing and future nonlinear loads is vital to study their ...
