Abstract: A space vector modulation (SVM) based hysteresis current controller (HCC) for the PWM rectifier is proposed. This technique utilizes all advantages of the HCC and SVM technique. The controller determines a set of state space vectors from a region detector and applies a space vector selected according to the HCC. A set of state space vectors including the zero vector to reduce the number of switchings is determined from the output signals of three comparators. A simple hardware implementation is proposed and experimental results of the SVM-based HCC are also shown.

TL;DR: In this paper, a Space Vector based Pulse Width Modulation (SVPWM) control technique for the three-phase PWM converter is proposed based on a synchronous reference frame model and the results show that the proposed model demonstrates better performance and properties compared to the traditional SPWM method and the method improves the dynamic performance of the closed loop drastically.
Abstract: A Space Vector based Pulse Width Modulation control technique for the three-phase PWM converter is proposed in this paper. The proposed control scheme is based on a synchronous reference frame model. High performance and efficiency is obtained with regards to the DC bus voltage and the power factor considerations of the PWM rectifier thus leading to low losses. MATLAB/SIMULINK are used as a platform for the simulations and a SIMULINK model is presented in the paper. The results show that the proposed model demonstrates better performance and properties compared to the traditional SPWM method and the method improves the dynamic performance of the closed loop drastically. For the Space Vector based Pulse Width Modulation, Sine signal is the reference waveform and triangle waveform is the carrier waveform. When the value sine signal is large than triangle signal, the pulse will start produce to high. And then when the triangular signals higher than sine signal, the pulse will come to low. SPWM output will changed by changing the value of the modulation index and frequency used in this system to produce more pulse width. The more pulse width produced, the output voltage will have lower harmonics contents and the resolution increase. Keywords—Power Factor, SVPWM, PWM rectifier, SPWM.

TL;DR: A zero current switching strategy of the PWM rectifier section during zero voltage vector periods of the inverter section is described and verified by computer simulation and experimental test on an induction motor drive.
Abstract: A converter without DC Link components needs snubber circuits, in order to assure the path of the load current during the dead-time period of the PWM rectifier section. In the snubber circuits, losses have been dissipated every time the switches of the rectifier section are turned on and turned off. During the zero voltage vector period of the inverter section, the load current does not flow in the PWM rectifier section. So if each switching operations of the PWM rectifier section are done in the zero voltage vector period, it is not necessary to assure the path of the load current. Therefore, snubber circuits are not necessary in the PWM rectifier section. In this paper, we describe a zero current switching strategy of the PWM rectifier section during zero voltage vector periods of the inverter section. The proposed strategy is verified by computer simulation and experimental test on an induction motor drive.

TL;DR: In this article, the experimental development of a four-wire single-phase to three-phase static converter for rural distribution system is presented, which is based on a front-end full-controlled PWM rectifier that handles the DC bus voltage regulation as well as improves the input power factor correction.
Abstract: This work presents the experimental development of a four-wire single-phase to three-phase static converter for rural distribution system. The converter topology is based on a front-end full-controlled PWM rectifier that handles the DC bus voltage regulation as well as improves the input power factor correction. In order to provide the three-phase four-wire system, a four-legged PWM voltage source inverter (VSI) is used at the output. The rectifier-inverter control strategy has been implemented in a digital processor (DSP), where a proposed PLL algorithm performs the rectifier synchronism. Component specification guidelines and control strategies are described. Complete models are implemented in an electromagnetic transient simulation package (PSCAD/EMTDC/spl trade/), where the converter is connected to a rural distribution network and is supplying three-phase and single-phase loads. Simulation results show that this converter can ride through a typical voltage sag condition that is very often in rural areas. The converter topology is composed of 12 IGBTs and can be implemented by two off-the-shelf three-phase PWM inverters. This availability can offer significant cost reduction. Experimental results are provided.

TL;DR: In this paper, a resultant voltage space vector-based voltage type PWM rectifier direct power control system was proposed, synthesizing adjacent voltage space vectors into a resultant vector with an amplitude the same as those of other nonzero vector space vectors to make the number of nonzero space vectors up to 12.
Abstract: The invention advances a resultant voltage space vector-based voltage type PWM rectifier direct power control system, synthesizing adjacent voltage space vectors into a resultant voltage space vector with an amplitude the same as those of other nonzero voltage space vectors to make the number of nonzero voltage space vectors up to 12. For further reducing power control errors, AC current harmonics and DC voltage fluctuation, it redivides input space into sectors. According to the new 12 voltage space vectors and divided sectors, it determines a new power control switch list. And computer simulation shows that it has good dynamic and static performances, making unit power factor, DC voltage fluctuation and AC current harmonics all reach national electric energy quality standard.
