Comparative analysis of active inrush current limiter for high-voltage DC power supply system

This paper performs analysis and verification of active inrush current limiter (AICL) using the MOSFET for high-voltage DC power supply. To active this, the performance characteristic of AICL is analyzed comparatively with inrush current limiters using inductor, NTC thermistor, and relay, which have been used to protect the devices. And utilized of AICL when is applied to high-voltage DC power supply is considered. In addition, a study on the relationship between the strength of a limited current, settling time and parameter of devices, which are organized AICL is performed. To verify effectiveness of AICL experiment is carried out using actual parameters. Through this study, utilization and reliability of AICL for high-voltage DC power supply is analyzed and evaluated theoretically and experimentally.
