“…Therefore, placing SCR in the A phase not only requires a higher rated current, but also leads to higher conductivity losses. In conclusion, the A-phase switching topology as a reference has the best performance in terms of loss and smooth mode transition compared to the other two options in the LSS topology [39,44].…”

Solid-state transfer switch (SSTS) becomes the most crucial technology for electric power transmission, distribution and control system. SSTS is useful in supplying the power to sensitive loads uninterruptedly and critical loads economically and efficiently. However, a few concerns could hamper the effectiveness of SSTS including voltage swell, sag, inappropriate structure, poor power factor and inefficient control methods. Hence, this paper comprehensively surveys the diverse SSTS topologies, applications, operations, issues, and future directions. The SSTS configuration, design, control system, benefits and shortcomings are discussed rigorously. A detailed comparative analysis of various SSTS are carried out concerning topologies, control operations and applications. In line with that, the different control models and schemes are narrated briefly. This paper also highlights existing challenges and issues before providing a few important future prospects to enhance the configuration and efficiency of SSTS. All the key information obtained from this review would be beneficial to the researchers and power system engineers to develop an advanced and efficient SSTS toward future performance enhancement.

“…Even though the parameter extraction of a valve tower is a complex topic, an accurate model must be used to well predict the behavior of the converter and to design suitable passive circuits to suppress overvoltages and to protect from unacceptable currents in the thyristor series [2]. Analytical methods to extract the stray capacitances of the valve and studies on their effects on thyristors' behavior have been developed, [3] - [4].…”

A high voltage thyristor converter is realized by many valve sections, whose volume is approximately occupied for only the 10% by thyristors and for the 10% by the relevant gate drivers. The remaining 80% is taken by passive auxiliary circuits, needed to protect thyristors during turn-on and turn-off commutations. This work represents a preliminary validation of an innovative architecture that aims to reduce the auxiliary circuit cost, volume, and weight of the overall valve, through the investigation of active, instead of passive solutions. The work starts from investigation of the phenomena behind the valve transient behaviors and proceeds with simulations and experimental tests, using a reduced scale circuit prototype. The match between the obtained results validates the investigated active configurations, confirming that the proposed solution can be used for improving thyristor valves.
