“…Especially for the multi-pulse transformer rectifiers, the power quality is almost "proportional" to the number of pulses of the transformers, while the overall volume also increases with the number of pulses. At the same time, it is also found that the control flexibility of the harmonics is enhanced when using the active Power Factor Correction (PFC) circuits (or more specifically employing active dc-link circuits) [2], [12], [21]- [24].

As an almost standardized configuration, Diode Rectifiers (DRs) and Silicon-Controlled Rectifiers (SCRs) are commonly employed as the front-end topology in three-phase Adjustable Speed Drive (ASD) systems. Features of this ASD configuration include: structural and control simplicity, small volume, low cost, and high reliability during operation. Yet, DRs and SCRs bring harmonic distortions in the mains and thus lowering the overall efficiency. Power quality standards/rules are thus released. For multiple ASD systems, certain harmonics of the total grid current can be mitigated by phase-shifting the currents drawn by SCR-fed drives, and thus it is much flexible to reduce the Total Harmonic Distortion (THD) level in such applications. However, the effectiveness of this harmonic mitigation scheme for multiple ASD systems depends on: a) the number of parallel drives, b) the power levels, and c) the phaseshifts (i.e., firing angles) for the corresponding SCR-fed drives. This paper thus adopts a particle swarm optimization algorithm to optimize the power levels and the firing angles for multi-drive systems considering a fixed number of drives when practically implemented. The optimization is done to minimize the THD level of the total current at the point of common coupling. Simulations with the optimized results are carried out and laboratory tests on a two-drive system are provided to demonstrate the phase-shifting harmonic mitigation scheme. Issues concerning the practical implementation of the optimal results in multi-drive systems are also addressed.

“…However, the performance cannot compete with that in single-phase PFC applications [12]. This is due to the inherent behavior of rectifiers in the case of a continuous conduction mode, where ideally the rectifiers draw currents of a rectangular shape with a conduction of 120 • [2], [24], [25]. Nevertheless, the configuration in Fig.…”

“…Many solutions have been reported to improve the power factor and decrease the current harmonics in single-phase [2], [3], and three-phase rectifiers [4], [5]. An state-of-the art update about Unity Power Factor Rectifier (UPFR) can be found in [6], [7] and [8]. The UPFR are characterized by a high power factor, and a fast dynamic response can be achieved in the output voltage if a proper control algorithm is implemented.…”

Abstract-This paper presents an improved variable hysteresisband current-control in natural frame for a three-phase unity power rectifier. The proposed control algorithm is based on three decoupled sliding-mode controllers combined with three independent Kalman filters. The use of Kalman filters instead of a non-adaptive state observer improves the quality of the estimated signals in presence of noise, increasing the immunity of the control loop in noisy environments. To reduce drastically the computational load in the Kalman algorithm, a reduced bilinear model is derived which allows to use a Kalman filter algorithm instead of an extended Kalman filter. A fast output-voltage control is also presented which avoids output-voltage variations when a sudden change in the load or a voltage sag appears. Moreover, a fixed switching frequency algorithm is proposed which uses a variable hysteresis-band in combination with a switching decision algorithm, ensuring a switching spectrum concentrated around the desired switching frequency. The overall control proposal has been fully integrated into a digital signal processor. Selected experimental results are introduced to validate the theoretical contributions of this paper.

“…Employing line commutated rectifier at the front-end stage imposes high level of input current harmonics. Although many harmonic mitigation solutions have been introduced [3], [4], most ASD manufacturers are still using conventional passive filtering technique (e.g., using inductor at ac-side or dc-side as shown in Fig. 1(a)) as a simple, reliable and an effective solution to some extent [4].…”

Abstract-In this paper, an electronic phase-shifting strategy has been optimized for a multi-parallel configuration of linecommutated rectifiers with a common dc-bus voltage used in motor drive application. This feature makes the performance of the system independent of the load profile and maximizes its harmonic reduction ability. To further reduce the generated low order harmonics, a dc-link current modulation scheme and its phase shift values of multi-drive systems have been optimized. Analysis and simulations have been carried out to verify the proposed method.
