The proposed method is able to significantly reduce the second-order harmonic component in the DC side current of the boost inverter without increasing other harmonic components.
Since a reliable design of the DC-link capacitor depends on an accurate estimation of its current ripple, this paper proposes analytical
A second band passing filter (BPF) feedback control loop is used to feedback the second harmonic ripple voltage in DC link into the statable modulation index. This strategy can
It shows that the dc-link current and voltage ripples in a three-phase inverter contain not only high-frequency harmonics, but also double fundamental frequency harmonics.
This paper proposes an analytical formulation-based minimization of DC link current ripples for interleaved parallel inverter systems. Parallel inverter systems find
A single-phase full-bridge inverter converts a DC voltage to an AC voltage by using a modulation technique to the bridge circuit. The bridge circuit is made of semiconductor switching devices
Since a reliable design of the DC-link capacitor depends on an accurate estimation of its current ripple, this paper proposes analytical equations to model the influence of dead
This reflects in current and voltage low-frequency ripple on the dc-link inverter side (i.e. at the double-fundamental frequency). A possible method to analyse this matter is through
Dc-link voltage ripple is a direct manifestation of the harmonic currents absorbed by the dc-link capacitor. Existing research primarily analyses its peak-to-peak and RMS values.
A second band passing filter (BPF) feedback control loop is used to feedback the second harmonic ripple voltage in DC link into the statable modulation index. This strategy can
In this paper, a method has been proposed for the analysis of dc-link ripple current rms value and voltage ripple considering the inverter antiparallel diode reverse recovery, and the impacts of
