In this paper, a real-time circulating current reduction method for parallel harmonic-
elimination pulsewidth modulation (HEPWM) inverters is proposed. HEPWM techniques are …

A shunt active power filter (APF) with current detection at the source side is considered as a
closed-loop system from the view of the whole power distribution system, which is expected …

In recent years, harmonic pollution has worried the power engineers considerably due to the
increased penetration of power-electronics-based devices in the utility grid. Monitoring of …

Electrical harmonic is an important issue on power quality of electrical systems. Therefore,
estimation of power harmonics are essential to design filters to be utilized in electrical power …

In order to reduce the maximum overshoot and undershoot of the DC-link voltage variation,
and minimize power ripples with low current distortion in accord with IEEE Std. 519–2014 …

A novel hybrid active power filter (HAPF) topology is proposed, which shows advantages of
the conventional HAPF and the LCL filter in terms of reduced dc-link voltage, lower switching …

In practice, because of different factors, the supply voltage (especially in the distribution
level) almost always has some degrees of imbalance and harmonic pollution. With …

This study proposes a control scheme with a new fundamental sequence components
extractor for grid interfaced distributed generation inverter under polluted grid conditions …

This paper presents real-time implementation of a new frequency adaptive least-squares-
Kalman (LSK) technique to monitor voltage flicker and fluctuations in power system. The …

A new digital phase-locked-loop (DPLL) method is proposed for single-phase grid-
connected power conversion systems in this paper. The analysis of a phase detector using …
