Single-phase power factor correction (PFC) circuits--a kind of front-end AC/DC converters--are ubiquitous in a variety of consumer electronic devices, including laptop adapters, LED driver power ...

Harmonics degrade power quality, reduce the operational lifespan of equipment, and can compromise system stability. This FAQ provides a technical overview of harmonics, their primary sources, and the ...

Abstract: The paper describes problem of isolating, evaluating and eliminating interharmonics of current using the example of the operation of an asynchronous electric motor operating at a variable ...

INTRODUCTION: The Perception Sensory Threshold (ST) for sinusoidal current stimuli at 5, 250, and 2,000 Hz is commonly used in the assessment of peripheral nerve fibers (C, Aδ, and Aβ, respectively).

In this installment of the Power Electronics Course, some techniques for reducing the harmonic content in the output voltage of converters will be explored. The harmonics in an output voltage are ...

Among all power factor correction (PFC) topologies, totem-pole bridgeless PFC provides the best efficiency; therefore, it is widely used in servers and data centers. However, closing the current ...

Electrical angle alignment of brushless dc (BLDC) motors is the process of determining how to apply electric current to the motor. In essence, it is determining where the magnets are with respect to ...
