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的产品营销经理Edward Ong解释了如何在使用CAPZero-2集成电路满足IEC 62368-1中最新的安全要求的同时减少空闲损耗。
Power Integrations SCALE-iDriver™ IGBT及功率MOSFET门极驱动器的推出,让高可靠性中低压电子电力系统的设计变得更为轻松容易。新驱动器集成了Power Integrations独有的FluxLink™技术 —— 一种固体绝缘磁感耦合通信技术。FluxLink接口和eSOP封装可提供符合VDE0884-11及IEC60747-17标准的加强电气绝缘,并且具有非常强电磁干扰(EMI)及磁场抗扰性,可使生产厂商轻松达到IEC61000-4-8及IEC61000-4-9标准。
装有电机的家用电器需要符合国际安全标准规定的专门要求。BridgeSwitch的集成半桥架构具有独特的下管和上管逐周期限流保护功能,并提供失效保障和冗余实现。因此,它可以充当保护装置,在非正常工作情况下保护电机,而不必依靠软件来控制故障状况。不必依赖控制软件来保护电机可以极大地简化和缩短安全合规过程。
