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.
High-voltage IGBT Driver Family with Reinforced Galvanic Isolation for Switching Semiconductors up to 1200 V
Designing reliable, low and medium voltage electronic power systems has been made easier with the introduction of the SCALE-iDriver™ IGBT and power MOSFET gate driver from Power Integrations. The new drivers incorporate Power Integrations’ proprietary FluxLink™, a solid insulator, magneto-inductive coupling, communications technology.
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.
In this June 23, 2020 webinar, PI Senior Product Marketing Manager Cristian IonescuCatrina discusses how market trends are driving changes in motor-drive inverter designs; exploring how designers can benefit from unique BridgeSwitch features and demonstrating why it is the perfect fit for the growing single-phase market.
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.
Simplified Product Safety Certification Through Hardware Based Motor Fault Protection with Bridgeswitch
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.
