    Capacitor banks are often utilized in conversion technologies of renewable energies for different reasons such as DC-link voltage regulation of power converters and power factor correction. During the capacitor bank energization process, voltage and current transients have negative impacts on the capacitor bank as well as the power quality of the system. In recent years, solid-state transient limiters have been proposed to rectify the problems relevant to capacitor bank switching. This paper presents a complete review of the recently proposed solid-state Capacitor Switching Transient Limiters (CSTLs). The objective of this review is to summarize and compare different methods for restraining the capacitor switching transients in terms of suppression capability, efficiency, power quality, complexity, cost, etc. Subsequently, a novel high-performance solid-state CSTL is proposed. During the energization process, the proposed limiter suppresses the transient currents through a limiting resistor. A bidirectional static switch bypasses the limiting resistor at the steady-state. The bidirectional static switch is controlled via a simple hysteresis controller based on Kalman Filter (KF) algorithm. In order to clarify the working principles, the proposed limiter is analyzed in detail. The performance of the limiter is assessed using some simulations in MATLAB/SIMULINK. In order to demonstrate the feasibility of the proposed limiter, a prototype of the device has been fabricated in the laboratory. The results of the simulations and experiments confirm the capabilities as well as some superiorities of this limiter in comparison with other solid-state CSTLs.
