Self-powered BridgeSwitch half-bridge motor driver ICs dramatically simplify the development of high-voltage single- or multi-phase BLDC motor drives.
Self-powered BridgeSwitch half-bridge motor driver ICs dramatically simplify the development of high-voltage single- or multi-phase BLDC motor drives.
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.
Power Integrations的產品營銷經理Edward Ong解釋瞭如何在使用CAPZero-2集成電路滿足IEC 62368-1中最新的安全要求的同時減少空閒損耗。
家用電器只要裝有馬達,就必須符合國際安全標準規定的特定要求。BridgeSwitch 的整合式半橋架構採用一套故障保護和備援措施,提供獨特的低壓側和高壓側週期性限電流保護。這可讓 BridgeSwitch 當作保護裝置,在發生異常運作狀況時保護馬達,而不必依靠軟體來控制故障狀況。由於不必依賴控制軟體來保護馬達,因此能夠大幅簡化並縮短安全合規性流程。
