모터가 내장된 가전 제품은 국제 안전 표준에 정의된 특정 요구 사항을 준수해야 합니다. BridgeSwitch의 통합형 하프 브리지 아키텍처는 페일 세이프 및 중복 구현을 통해 고유한 로우 사이드 및 하이 사이드 사이클별 current limit 보호 기능을 갖추고 있습니다. 따라서 고장 조건을 제어하는 소프트웨어에 의존하지 않고도 비정상적인 작동 조건에서 모터를 보호하는 보호
Power Integrations의 제품 마케팅 매니저 인 Edward Ong는 유휴 손실을 줄이는 동시에 CAPZero-2 집적 회로를 사용하여 IEC 62368-1의 최신 안전 요구 사항을 충족시키는 방법을 설명합니다.
High performance motor drives commonly use field-oriented control (FOC) since it offers smooth and efficient operation throughout the entire speed range. BridgeSwitch offers a unique function by providing a small signal output that is an instantaneous representation of the positive phase current. This function can eliminate commonly used discrete current
BridgeSwitch allows building compact, high-voltage brushless DC motors drives without having to use a physical heatsink. This document discusses techniques for optimizing the PCB layout, including device arrangement, inter device distance, and copper clad area, all of which play an important role in the thermal performance of the device.
The efficiency and size benefits of SiC devices have been enthusiastically embraced by designers of industrial, automotive, traction systems and photovoltaic power conversion. To provide more detail, the lower sheet resistance of wide-bandgap SiC materials (typically 1/100th that of conventional silicon) results in smaller devices for a given current capacity—valuable
Integrating current sensing into the low-side switch enhances system efficiency and simplifies predictive maintenance for three-phase motors.
