Thanh Dat Nguyen(웬탄닷),Chi Trung Ngo(오치충),Seungbum Baek(백승범),Jong-Phil Hong(홍종필) 한국통신학회 2021 한국통신학회 학술대회논문집 Vol.2021 No.6
This paper presents a method of improving accuracy in designing impedance matching network for Acousto-Optic Tunable Filters (AOTF) by considering the effect of wire connection. The measured gain S21 of implemented impedance matching network has a BW- 6dB of 49% from 17.54 to 28.95 MHz by applying this method.
A study on the reset program to detect insulation faults in the power supply system
Pham Van Khanh(팜반카인),Nguyen Thanh Dat(웬탄닷),Jong-Phil Hong(홍종필) 한국통신학회 2021 한국통신학회 학술대회논문집 Vol.2021 No.6
This paper presents a reset program that is used throughout the operation of the Insulation Monitoring Device (IMD) to quickly detect insulation fault when an unexpected insulation fault occurs in the Power Supply Systems (PSS). The reset program can improve the response time up to 4 times.
