“…There are many ways to provide control of threephase PFC. Methods of immediate network current curve shaping [8][9][10] and direct power control [11][12][13][14][15] are the most widely used. Here we have chosen the method of direct power control.…”

Nowadays three-phase power factor correctors (PFC) became widely used. This is dictated by strict requirements of the international electrical technical commission standards to harmonic composition of current supplied by three-phase industrial network. New schematic technical version of three-phase PFC having direct power control and improved efficiency factor is presented. Mathematical description of power component and control system taking in account its functioning depending upon asymmetrical three-phase input voltage was fulfilled. The electrical processes in the presented PFC was analysed by means of computer simulation. The obtained results are of interest to the persons engaged in the development of electrical energy systems and complexes to which higher requirements in respect to power loss reduction and reliable functioning in case of three-phase asymmetrical industrial network are imposed.

“…In recent years, with the fast development of communications, electric vehicle (EV) charging station and computer industry, the safe and reliable operation of high‐voltage DC power supply system has become an important research topic all over the world. VIENNA rectifier is a three‐phase three‐level Boost‐type circuit which was first developed and proposed by Kolar in 1997. Specifically, compared with other three‐level bridge‐type topologies, the three‐phase three‐level Boost‐type VIENNA rectifier (Fig.…”

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.

“…Compared with DCC, DPC has advantages of simple structure, fast dynamic response, high efficiency, and wide applicability [8]. Currently, many advanced DPC strategies have been proposed, such as predictive DPC (P-DPC) [9], deadbeat DPC [10], and slide-mode DPC [11]. In the single-phase PWM converter 2 of 18 system, instantaneous power estimation is more complicated than in the three-phase system, which limits the development of DPC schemes in single-phase systems [12].…”

The conventional control method for a single-phase cascaded H-bridge (CHB) multilevel converter is vector (dq) control; however, dq control requires complicated calculations and additional time delays. This paper presents a novel power control strategy for the CHB multilevel converter. A power-based dc-link voltage balance control is also proposed for unbalanced load conditions. The new control method is designed in a virtual αβ stationary reference frame without coordinate transformation or phase-locked loop (PLL) to avoid the potential issues related to computational complexity. Because only imaginary voltage construction is needed in the proposed control method, the time delay from conventional imaginary current construction can be eliminated. The proposed method can obtain a sinusoidal grid current waveform with unity power factor. Compared with the conventional dq control method, the power control strategy possesses the advantage of a fast dynamic response. The stability of the closed-loop system with the dc-link voltage balance controller is evaluated. Simulation and experimental results are presented to verify the accuracy of the proposed power and voltage control method.
