This paper investigates a 12-pulse voltage source converter (VSC) for harmonics mitigation in high voltage DC (HVDC) system. The most promising features of the VSC based system are compact and light weight design, short installation and commissioning periods, low operation and maintenance cost and flexibility in control. A current multiplier approach is proposed in this paper inside the voltage control loop for power quality (PQ) improvement at AC mains. The proposed system is designed, modeled and its performance is simulated in MATLAB-SIMULINK environment. The simulated results are presented to demonstrate an improved power quality at the AC mains in term of total harmonic distortion and power factor of the VSC based HVDC system under various transient conditions such as variation of load, load unbalancing and voltage sag in power supply.

“…The most critical issue is how to substitute the "null-vector" time of the period T m , which is normally carried out by the two null vectors V 0 0 and V 0 7 in the SVPWM of the conventional SSTPI (Van Der Broeck and Van Wyh, 1984;Van Der Broeck and Skudelney, 1988;Fukuda et al, 1990;Holtz, 1993;Jacobina et al, 1995;Zhou and Wang, 2002;Elbadsi et al, 2005). To do so, an idea consists of applying two vectors opposite among V 0 1 to V 0 4 in order to compensate the corresponding effects.…”

“…Of particular interest are reduced topologies of the inverter feeding the electric motor used as a propeller. The four-switch three-phase inverter (FSTPI), with just two legs, is currently considered as a viable candidate to substitute the conventional six-switch three-phase inverter (SSTPI) (Van Der Broeck and Van Wyh, 1984;Van Der Broeck and Skudelney, 1988;Fukuda et al, 1990;Holtz, 1993;Jacobina et al, 1995;Zhou and Wang, 2002;Elbadsi et al, 2005). Furthermore, and in some applications, there is currently a trend to carry on feeding an electric motor with the FSTPI in case of troubles with one leg of the SSTPI.…”

Purpose -The paper aims to discuss the comparison of the performance of four space-vector pulse-width modulation (SVPWM) strategies dedicated to four-switch three-phase inverters (FSTPI). Design/methodology/approach -The comparison is based on three comparison criteria: the total harmonic distortion, the switching loss factor, and the quality factor. The comparison is extended to the FFT of the phase currents and to the analysis of the ripples of the electromagnetic torque of the induction motor. Findings -It has been clearly shown that the basic SVPWM strategy of the conventional six-switch three-phase inverter (SSTPI) offers better performance than those of the four FSTPI-SVPWM strategies. This said, it has been found that the performance of two among the four FSTPI-SVPWM strategies tend to those of the SSTPI-SVPWM basic strategy, especially in high switching frequencies.Research limitations/implications -The work should be extended by an experimental validation of the simulation results. Practical implications -The established results open up crucial benefits from the point of view of cost-effectiveness and volume-compactness improvements of induction motor drives especially in large-scale industries such as the automotive one where electric and hybrid propulsion systems are currently regarded as an interesting alternative to substitute or to assist the thermal propulsion systems. Originality/value -The implementation in the FSTPI feeding an induction motor of SVPWM strategies exhibiting acceptable performance, which tend to those yielded by the SSTPI-SVPWM basic strategy especially in high switching frequencies, is extended here.

“…iL has a pulsed shape, thus, it cannot be use directly because an average value of iL over a sampling period is required. An average of iL can be obtained by using a highpass filter [5] or by detecting power in the DC link [6]. In this paper, we propose a different method because the method illustrated in [5] introduces a time delay and the method illustrated in [6] requires complicated hardware.…”

A vector controlled IM drive system consisting of a boost rectifier, inverter and induction motor is considered with emphasis placed on the rectifier side. Boost rectifiers can supply DCpower while maintaining a sinusoidal AC current with an arbitrary value of fundamental power factor. They are required to simultaneously control both the DC voltage and the reactive current. A DSP-based discrete-time integral-type optimal regulator is considered for the control, because it can provide a robust control system and can accommodate for the computational delay in the output. To obtain higher control performance a DC load current feedforward signal from the inverter side is added
