스위칭 전원 공급 장치(스위칭 전원 공급 장치 또는 스위칭 컨버터라고도 함)의 개략도에 대한 자세한 설명은 고주파 전기 에너지 변환 장치 및 전원 공급 장치의 유형입니다.
 그 기능은 다양한 형태의 아키텍처를 통해 정확한 전압을 사용자가 요구하는 전압 또는 전류로 변환하는 것입니다.

1. 주 회로

임펄스 전류 제한: 전원이 켜지는 순간 입력 측의 임펄스 전류를 제한합니다.

입력 필터: 그 기능은 전력망에 존재하는 잡동사니를 걸러내고 기계 생성을 방해하는 잡동사니를 전력망으로 되돌리는 것입니다.

정류 및 필터링: 전력 그리드의 AC 전원 공급 장치를 보다 부드러운 DC 전원으로 직접 정류합니다.

반전: 정류된 DC 전원을 고주파 스위칭 전원 공급 장치의 핵심 부분인 고주파 AC 전원으로 변환합니다.

출력 정류 및 필터링: 부하 요구 사항에 따라 안정적이고 안정적인 DC 전원 공급 장치를 제공합니다.

2. 제어 회로

한편, 샘플은 설정 값과 비교하여 출력 단부에서 가져온 다음 인버터를 제어하여 펄스 폭 또는 주파수를 변경하여 안정적인 출력을 보장합니다. 한편, 테스트 회로에서 제공하고 보호 회로로 식별된 데이터를 기반으로 제어 회로를 제공하여 전원 공급 장치에 대한 다양한 보호 조치를 제공합니다.
