Bridgeswitch故障状态通信接口代码库

This archive contains a code library and application programming interface (API) for an exemplary implementation of the BridgeSwitch IC FAULT communication interface using a Cypress PSoC microcontroller. It includes a PSoC Creator IDE version 4.1 project file, C++ code examples to support the API, and documentation on the available functionality.

Direct Use of Bridgeswitch Current Sense Signal Output in Field Oriented Control of Brushless DC Motors

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 sense resistors and associated amplifiers, thereby reducing cost and design complexity.

通过BridgeSwitch基于硬件的电机故障保护功能来简化产品安全认证

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。
