Three-phase multiplexing arm modular multilevel converter (TPMA-MMC) possesses cost-efficiency advantage by employing a pair of multiplexing arms. However, the narrow multiplexing arm energy regulation period results in the limited modulation range [0.82, 1]. This article proposes a wide multiplexed period operation principle with the multiplexing arm energy regulation period being extended to one...Show More
By using the vector control for permanent magnet synchronous motor (PMSM), the current static decoupling is realized, however, the dynamic coupling still exists. Some conventional methods achieve dynamic decoupling to some extent but these methods depend on specific motor parameters. To solve this problem, this paper proposes a decoupling control method applied to PMSM drives via vector control an...Show More
For the dual-active-bridge (DAB) converter, the adoption of high-frequency transformer provides galvanic isolation, but also brings the possibility of dc bias. In this paper, the calculation methods for dc bias are derived in details. Hence, the dc bias magnetizing current can be predicted considering the inconsistency of semiconductor switches and driver signals. In other words, if the maximum pe...Show More
As direct current transmission (HVDC) has been improving rapidly, the power flow control of which is increasingly popular and can be realized by the DC power flow controller. In this paper, a novel DC power flow controller (DCPFC) is proposed with the advantages of simpler strategy, little side effect on direct current system, no auxiliary power source and wide applications. A simulation model wit...Show More
With the rapid development of HVDC transmission and the increasingly complex structure of DC networks, DC power flow control and short circuit fault problems become prominent. Based on the technology of interline direct current power flow controller and fault suppression, this paper proposes a new compound controller for power flow and short-circuit fault in DC grid. The device can not only realiz...Show More
