“…A comparison on THD of 2L-VSI, 3L-NPC and matrix converter with PMSG is undertaken in [51] and 3L-NPC provides the lowest value of THD among the three topologies. This result verifies that THD decreases with increasing number of levels [46]. Different PEC topologies consist of components with variable numbers and sizes that result variation in cost.…”

“…In terms of power losses, it is widely reported that ML VSCs have less power losses than 2L VSIs with 3-Level Neutral Point Clamped VSIs (3L-NPC) having even lower amount of losses over 3-Level Flying Capacitor VSIs (3L-FLC) [46][47][48]. This advantage of 3L-NPC, however, inherits poor power loss distribution, which is the main drawback of 3L-NPC as mentioned previously.…”

“…In [46,47], uneven loss distribution of 3L-NPC is reported along with other topologies such as 2L-VSI and 3L-FLC, which have even distribution. As mentioned previously, ANPC is the topology to reduce the unevenness among the switching devices and it is reported that 3L-ANPC possess an advantage of 3L-FLC on its natural doubling of switching frequency, without flying-capacitors [50].…”

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.

“…The power converters are based on two-level voltage-source converter (VSC) topology [52] and have been manufactured by Belgian company Triphase [53]. Each converter is additionally fitted out with an auxiliary diode rectifier and a step-up transformer that enable to feed the converter DC-bus in order to operate as a power source.…”

“…Multilevel inverters have become the dominant solution for high power electrical drives [1], [2], [3], [4]. Moreover, the three-phase, three-level neutral-pointclamped voltage-source converter (3L-NPC VSC) is one of the most used converters for medium voltage drives [3], [2], [1], [5].…”

The neutral-point balancing of 3L-NPC converter has been studied in many works in the past. However, all state-of-the-art methods have in common that the information of the energy-flow direction is needed. Recently, Direct Dead-time Control (DDTC) has been presented which controls the converter dead-times to balance the dc-link independent from the energy-flow direction. This paper presents an experimental investigation of DDTC for different load conditions and control schemes.
