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.
Impact of Printed Circuit Board Layout on Device Temperature in 3-Phase Inverters Using BridgeSwitch
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.
