“…Split DC-link topology provides a neutral common point for three-phase VSI, 3P3W, and 3P4W systems [142,143], and uses two connector pairs to split the single leg, thus providing a neutral path or midpoint connection [144,145], as depicted in Figure 11. The three-leg split capacitor and four-leg VSI-based topologies are the most demanding configurations for the 3P3W APF system.…”

Abstract:This study summarizes an analytical review on the comparison of three-phase static compensator (STATCOM) and active power filter (APF) inverter topologies and their control schemes using industrial standards and advanced high-power configurations. Transformerless and reduced switch count topologies are the leading technologies in power electronics that aim to reduce system cost and offer the additional benefits of small volumetric size, lightweight and compact structure, and high reliability. A detailed comparison of the topologies, control strategies and implementation structures of grid-connected high-power converters is presented. However, reducing the number of power semiconductor devices, sensors, and control circuits requires complex control strategies. This study focuses on different topological devices, namely, passive filters, shunt and hybrid filters, and STATCOMs, which are typically used for power quality improvement. Additionally, appropriate control schemes, such as sinusoidal pulse width modulation (SPWM) and space vector PWM techniques, are selected. According to recent developments in shunt APF/STATCOM inverters, simulation and experimental results prove the effectiveness of APF/STATCOM systems for harmonic mitigation based on the defined limit in IEEE-519.

“…For the other cases, same calculations can be easily made to obtain the voltage production capabilities, as it is provided in table I [16,21]. After reconfiguration, the switches currents will remain the same, and the current of faulty phase will pass through the capacitors of the DC-link.…”

“…In [20] a form of this converter has been suggested for an AC/AC conversion system. In [21] all the three possible structures of the four-leg converter are studied and the suitability of this converter is approved. It is shown that when the input and output frequencies are the same, reduction of the required DC-link voltage is possible.…”

This paper presents an investigation on a nonredundant topology for two-leg fault at a back-to-back converter-fed induction motor drives. In the case of faults occurring in any two inverter legs, the six-leg back-to-back converter can be changed to a four-leg back-to-back converter by employing one motor phase connected to the rectifier leg and another phase connected to the dc-link capacitor mid-point for fault tolerant operation. The fourleg back-to-back converter is very attractive for the merit of not requiring additional power switches for fault-tolerant. However, as the shared-leg connection between inverter and rectifier, the rectifier and the motor drive are deeply coupled. A novel scheme based model predictive control (MPC) is presented to achieve independent control of the grid and motor currents. The voltage limitation for independent control of the rectifier and motor drive is analyzed and the dc-link voltage utilization is improved by capacitor voltage suppression. With the proposed scheme, the output speed range of the converter is degraded but other performances, such as output torque capability, unity power factor and the dynamic response, are maintained after faults occur. Finally, the control concept is verified by a TMS320F28335 DSP-based prototype.
