Abstract

In this paper, the two PCB design method results of boost converters are simulated with same circuit device parameters. One is modeled with microstrip structure and the other is modeled two layers structure without reference plane. Between devices of each circuit are routed 5 centimeters. When the switching frequency is operated 100kHz, the overshoot by signal reflection and the noise characteristics by frequency spectrum for the output voltage and current of the power switch is compared and analyzed using simulation.

본 논문에서는 동일한 회로소자 파라미터를 적용한 상태의 boost converter를 microstrip 구조의 PCB설계와 reference plane을 적용하지 않은 양면 PCB설계에 대하여 각각의 회로를 모델링하였다. 각 회로의 소자사이의 배선거리를 동일하게 5cm로 구성하였고, 스위칭 주파수를 100kHz로 스위칭할 경우 전력 스위치의 출력 전압/전류에서 발생하는 신호 반사에 의하여 발생하는 overshoot와 주파수 스펙트럼에서 발생하는 잡음을 시뮬레이션을 통하여 비교 분석하였다.
