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.
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.
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.
Household appliances incorporating motors need to comply with specific requirements defined by international safety standards. The unique features of the integrated half-bridge architecture of BridgeSwitch enable it to perform as a protective device protecting the motor during abnormal operation conditions without having to rely on software for controlling the fault condition, simplifying and shortening the safety compliance process.
