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.

Edward Ong, product marketing manager at Power Integrations, explains how to reduce idle losses while meeting the latest safety requirements in IEC 62368-1 using Power Integrations’ CAPZero-2 IC.

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
