Abstract

DC/DC switching power converters are commonly used to generate a regulated DC output voltages with high efficiencies from different DC input sources. The voltage mode DC/DC converter utilizes MOSFET (metal-oxide semiconductor field effect transistor), inductor, and a PWM (pulse-width modulation) controller with oscillator, amplifier, and comparator, etc. to efficiently transfer energy from the input to the output at periodic intervals. The fundamental boost converter and a buck converter containing a switched-mode power supply are studied. In this paper, the electrical characteristics of DC/DC power converters are simulated by program of SPICE, and the PWM controller is implemented to check the operation. In addition, power efficiency is analyzed based on the specification of each component.

DC/DC컨버터는 임의의 직류전원을 부하가 요구하는 형태의 직류전원으로 변환시키는 전력변환기이다. 전압모드 DC/DC 컨버터는 주기적으로 입력측에서 출력측으로 전달되는 에너지를 제어하는 기능을 수행하기 위해 MOSFET(산화물-반도체 전계 효과 트랜지스터), 인덕터, PWM 제어기(오실레이터, 연산증폭기, 비교기로 구성)를 이용한다. 본 논문에서 PWM(펄스폭 변조) 모듈과 스위칭모드로 제어하는 기본적인 승압과 강압컨버터를 연구하고, 전기적 특성을 SPICE로 시뮬레이션을 수행하며, 전력의 효율을 각 소자의 변화와 사양에 따라 분석하는데 있다.
