“…It is well-known that SHE strategy provides good harmonic performance in spite of the low switching frequency due to its harmonic elimination nature [53,65]. Another advantage is the reduction on its switching loss due to the low switching frequency [36].…”

“…Another advantage is the reduction on its switching loss due to the low switching frequency [36]. However, there are some disadvantages exist including its heavy computational cost and narrow modulation range [59,65]. There are many researches on SHE such as NP balancing for 3L-NPC [36] and the increase of the number of eliminating low-order harmonics with simple in formulation [66].…”

This paper focuses on the wind energy conversion system (WECS) with the three main electrical aspects: 1) wind turbine generators (WTGs), 2) power electronics converters (PECs) and 3) grid-connection issues. The current state of wind turbine generators are discussed and compared in some criteria along with the trends in the current WECS market, which are 'Variable Speed', 'Multi-MW' and 'Offshore'. In addition, the other crucial component in the WECS, PECs will be discussed with its topologies available in the current WECS market along with their modulation strategies. Moreover, three main issues of the WECS associating with the grid-connection, fault-ride through (FRT) capability, harmonics/interharmonics emission and flicker, which are the power quality issues, will be discussed due to the increasing responsibility of WECS as utility power station. Some key findings from the review such as the attractiveness of BDFRG are presented in the conclusion of this paper.

In this paper, a 5th and 7th harmonic suppression technique for a 2-level VSI fed IM drive, by using capacitive filtering is proposed. A capacitor fed 2-level inverter is used on an open-end winding induction motor to suppress all 5th and 7th order harmonics. A PWM scheme that maintains the capacitor voltage, while suppressing the harmonics is also proposed. The proposed scheme is valid for the entire modulation range, including overmodulation and six-step mode of operation of the main inverter.
