Traditional duty‐cycle or phase‐shift modulation is inadequate for achieving a balanced current‐stress distribution during the startup of full‐bridge DC/DC converters. As converter power capacity increases, these limitations not only restrict the startup

This paper revisits loss model control (LMC) of the 3‐phase induction motor (IM) and presents a robust LMC algorithm for medium‐sized pump drives. Compared with other power loss reduction algorithms for IM, the presented one has the advantages of fast and smooth flux adaptation, high accuracy, and versatile implementation.

Abstract Hybrid switching technologies such as zero voltage switching (ZVS) and zero current switching (ZCS) are widely accepted to protect DC power systems from different kinds of faults. However, in some cases such as the protection of DC generators in the electrical distribution system of modern ships, different protection strategies are needed for ...

Abstract Grid connection of remote offshore wind‐parks uses high‐voltage direct current technology and in order to reduce costs and losses and maximise profitability, semiconductor power losses must be minimised. To properly choose the semiconductors, it is necessary to estimate their losses for a large number of operating conditions.

A new DC-DC converter linking LCC-HVDC transmission networks [PDF]
Transferring bulk power via high voltage direct current (HVDC) transmission is dominated by line commutated converters (LCC). This is due to the robustness and higher ratings of the thyristors as well as the higher converter efficiency.

Design criteria of solid‐state circuit breaker for low‐voltage microgrids
Abstract Solid‐state circuit breakers (SSCB) show great promise to become the key element in the protection of low‐voltage direct current microgrids. SSCBs operate in the microsecond range and employ semi‐conductor devices that have strict safe operation area limits.
