“…It suffers from serious generator de-rating caused by highly distorted armature currents. To solve this problem, one can employ suited three-phase SMRs [14][15][16][17][18][19]. From the compromised considerations in switch number and control performance, the Vienna rectifier [14,[16][17][18][19] using only three switches is a better choice.…”

This paper presents the development of a wind interior permanent-magnet synchronous generator (IPMSG) based DC micro-grid and its operation control. First, the derated characteristics of PMSG systems with various AC/DC converters and operation controls are comparatively analyzed. Then the IPMSG followed by three-phase Vienna switchmode rectifier (SMR) is developed to establish the common DC bus of DC micro-grid. Good developed power and voltage regulation characteristics are achieved via the proposed commutation tuning, robust current and voltage controls. Second, a single-phase three-wire (1P3W) inverter is constructed to serve as the test load. Good AC 220V/110V output voltage waveforms under unknown and nonlinear loads are preserved by the developed robust waveform tracking control scheme. Third, a battery energy storage system (BESS) is established, and the fast energy storage support response is obtained via the proposed droop control approach with adaptive predictive current control method. In addition, a chopped dump load is equipped to enhance the energy balance control flexibility.

“…If higher efficiency is desired, the bridgeless DCM threephase SMR presented in [35] can be employed. To yield good line drawn current waveform tracking control with the minimum switch number, the three-phase three-switch (3P3SW) Vienna SMR [46,47] is a good choice. However, these two types of SMRs possess only AC-to-DC unidirectional power flow capability.…”

Power Quality Issues in Distributed Generation

A switch-mode rectifier (SMR) can provide adjustable and well-regulated DC output voltage from the available AC source with good line drawn power quality. Depending on the input/output voltage transfer characteristics, the schematics, the operation quadrant, and control, SMRs possess many classifications and application. Typical potential application examples include grid powered motor drives, battery chargers, various power electronic facilities, micro-grids, and grid-connected battery energy storage system (BESS), etc. In micro-grids, the SMR can be employed as the AC generator-followed converter to yield better generating efficiency. The SMR operation of its grid-connected inverter let the grid-to-microgrid (G2M) operation be conductable in addition to the microgrid-to-grid (M2G) operation. As for the electric vehicle (EV), the bidirectional inverter can be arranged to perform G2V/V2G operations in idle case, wherein the SMR operation is made in G2V battery charging.To promote the application potential and improve the operation performance of SMRs, this article presents the operation controls and applications of SMRs in microgrid systems incorporating BESS and EV as supplemental facilities. First, the classifications, operation principle, and some key issues of SMRs are explored.Secondly, the configuration of the studied system is introduced. Third, the controls and operations of SMRs in micro-grid, wind generators, and grid-connected interface power converters are described. Then the ones in BESS (B2G/G2B) and EV are introduced. Finally, some conclusions and suggestions are given.

“…Considering proved advantages of multilevel converters such as low switching frequency, low harmonic distortion and high power conversion, they have been widely used in various industries [17][18][19]. Many multilevel rectifiers called bridgeless topologies are studied in the literature mainly including threelevel ones [20][21][22][23][24]. Some five-level topologies have been also introduced that are using hysteresis current control or another complicated controllers that makes switching frequency higher than standard levels results in higher power losses and lower efficiency.…”

Abstract-A multilevel boost PFC (Power Factor Correction) rectifier is presented in this paper controlled by cascaded controller and multicarrier pulse width modulation technique. The presented topology has less active semiconductor switches compared to similar ones reducing the number of required gate drives that would shrink the manufactured box significantly. A simple controller has been implemented on the studied converter to generate a constant voltage at the output while generating a five-level voltage waveform at the input without connecting the load to the neutral point of the DC bus capacitors. Multicarrier PWM technique has been used to produce switching pulses from control signal at a fixed switching frequency. Multi-level voltage waveform harmonics has been analyzed comprehensively which affects the harmonic contents of input current and the size of required filters directly. Full experimental results confirm the good dynamic performance of the proposed five-level PFC boost rectifier in delivering power from AC grid to the DC loads while correcting the power factor at the AC side as well as reducing the current harmonics remarkably.
