1 THE JOURNAL OF KOREAN INSTITUTE OF ELECTROMAGNETIC ENGINEERING AND SCIENCE Jun.; 29(6), ISSN (Print)ISSN X (Online) Analysis and Performance Improvement of Integrated E1 Pulse Generator for EMP Protection Performance Test 김영진 강호재 정영경 윤동기 박용배 Young-Jin Kim*, **Ho-jae Kang**Young-Kyung Jeong***Dong-Gi Youn***Yong Bae Park* 요약 HEMP(High-altitude Electromagnetic Pulse) EMP HEMP E1. E1 Marx Generator, (30350 kv) Tesla Transformer. E1,,,. Tesla Transformer E1,. Abstract We herein investigate the E1 pulse for evaluating the conducted performance of transmission lines connected to the electromagnetic pulse protection facilities against a conducted high-altitude electromagnetic pulse threat exposed to an external electromagnetic environment. The existing E1 pulse generator uses the Marx generator high-voltage step-up method; however, in this research, we used the Tesla transformer method to easily change the broadband output voltage(30 to 350 kv). We also analyzed the controller, power supply, high-voltage booster, and pulse-shaping device. The E1 pulse performance using the Tesla transformer was predicted through simulations and validated by measurements. Key words: HEMP(High-Altitude EMP), Pulse Generator, EMP Protection Facility, Tesla Transformer, Marx Generator. 서론 30 km (HEMP), [1].
