“…However, there is very little systematic research on large signal stability analysis of MVDC systems due to the lack of reliable large-signal models of the converters. Youssef et al [24] use the state space averaging method or controlled voltage and current source to replace the power converter switches in the circuit. The duty ratio is embedded in the main parameters of the model so that the model is different according to operating conditions, necessitating a case-by-case analysis depending on the operating mode.…”

This paper investigates the influence of control bandwidth on the stability of loads, which are interfaced through power electronic converters and are fed from a dc power source. When tightly regulated, these loads exhibit a constant power load (CPL) behavior. It is shown here that the ideal CPL assumption, prevalent in literature, may not represent the worst case in real-life applications. If the control bandwidth of the load is sufficiently high, the load behaves like a CPL, and the system stability margin decreases with the increase in output power. However, in a practical range, with a lower control bandwidth, the system stability margin is influenced critically by the converter's characteristic impedance, as well as its output power. Under these conditions, the minimum stability margin may occur at a low-power range.

“…1) has proven to be a cost-effective and very efficient solution, maximizing the power density of industrial motor drives, active filters and three-phase power supplies for EV charging station and telecommunication applications. [4] However, as a current force rectifier, the nonlinear dynamic behavior and threelevel structure of the VIENNA-type rectifier makes the controller design very complex to achieve unity power factor and eliminate the specific harmonic pollution. [5] To improve the power density of the VIENNA rectifier effectively, various digital control strategies have been proposed on the control of VIENNA rectifier.…”

A three‐phase three‐level VIENNA rectifier has been widely used in the data center DC power supply and AC/DC hybrid power supply system with the advantages of without dead‐time, low switch voltage stress and small grid‐current harmonic. However, the performance of grid current strongly depends on the controller parameter, and the unreasonable controller parameter may deteriorate the grid current. To effectively improve the static and dynamic performance of grid current, a new kind of carrier‐based pulse width modulation scheme based on the double closed‐loop discrete sliding mode strategy is put forward. Further, a modified exponential reaching law is presented to effectively improve the shaking shock effect caused by the traditional sliding mode surface and the neutral voltage dc wave suppression strategy is then presented. To verify the correctness and effectiveness of the proposed sliding mode control strategy, a complete simulation model and experimental prototype platform under the digital control is established, the detailed theoretical analysis and design method of the proposed control strategy are presented. The simulation and experimental results show that the steady and the transient performance of the grid current with the proposed control strategy are effectively improved, and the neutral voltage in dc side is kept balanced at the same time. © 2020 Institute of Electrical Engineers of Japan.

“…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.
