Three-level NPC inverter based new DSTATCOM topologies and their performance evaluation for load compensation

A review of distribution static compensator

“…Split capacitor topology with LCL filter is reported in [80]. Chopper technique with dc bus in split capacitor topology for harmonic compensation, power factor correction, and load balancing is reported in [81,82].…”

“…A comparative study of different topologies of nonisolated VSCbased 3P4W DSTATCOM without transformer is carried out based on critical reviews of publications [69][70][71][72][73][74][75][76][77][78][79][80][81][82] and provided in Table 3. The detailed comments are included to highlight the important aspects of each topology.…”

A new balancing three level three dimensional space vector modulation strategy for three level neutral point clamped four leg inverter based shunt active power filter controlling by nonlinear back stepping controllers

“…Various multilevel inverters configurations are proposed and used in the harmonics elimination and reactive power compensation, such as the multilevel Cascade H-bridge Inverter [11][12][13][14], Flying Capacitor Multilevel Inverter [15][16][17], and the multilevel neutral-point-clamped (NPC) Inverter [18][19][20][21][22][23]. The NPC inverters are the most widely used topology and successfully employed in medium and high power applications in the harmonics elimination and reactive power compensation for electrical networks [18].…”

“…Switches inverter based SAPF suffers from variation switching frequency problem of hysteresis controller and it is also not fully effective in the application of SAPF due to the weak quality of SAPF output voltages and the unbalanced of dc bus voltage capacitors. Two modifications in the three-level NPC inverter based Distribution Static Compensator (DSTATCOM) are suggested by Gawande et al [21] to developed an news configurations of three-level NPC inverter based on hysteresis controller for circumvent the unbalance dc bus voltage capacitors problem, in these works not take into account the problem of variation switching frequency.…”

High performance operation for a four-leg NPC inverter with two-sample-ahead predictive control strategy

“…The three-level neutral-point-clamped (NPC) inverter is the most widely used configuration in many medium voltage (MV) (from 2.3 to 4.16 kV) industrial applications [1,2]. This power converter has several advantages: (1) high voltage capability, (2) reduced common mode voltages, (3) nearly sinusoidal output voltage, (4) low dv/dt's, which can reduce the electromagnetic interference, and (5) small or even no output filter [3].…”
