Power Integrations의 제품 마케팅 매니저 인 Edward Ong는 유휴 손실을 줄이는 동시에 CAPZero-2 집적 회로를 사용하여 IEC 62368-1의 최신 안전 요구 사항을 충족시키는 방법을 설명합니다.
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
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. The FluxLink interface and eSOP package provide
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.
Maintaining SiC MOSFET Efficiency and Protection without Compromise
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
Performance Comparison of Using Shunt-Based and Integrated Current Sensing for Sensorless Field-Oriented Control
Integrating current sensing into the low-side switch enhances system efficiency and simplifies predictive maintenance for three-phase motors.
