Demand for low-cost, robust motor drives has spurred increased use of sensorless vector control of induction and BLDC motors — in everything from consumer products to industrial applications, in ...

A Z-source Inverter (ZSI) is a DC-to-AC converter that can perform both buck and boost functions as a single stage. A unique attempt of ZSI is the shoot through state, by which two switches of the ...

Brushless DC (BLDC) motors offer many operating attributes in performance and controllability, but they may require a position (rotation) sensor such as an encoder, resolver, or Hall-effect device to ...

[Davide Gironi] shows us how to implement a sensorless brushless DC motor controller (sensorless BLDC) using an ATmega8 microcontroller. In order to control a BLDC motor you need to know its ...

Turkish researchers have developed an algorithm to distinguish faults and changes in PV plant output. The sensorless method only uses electrical data gathered from the DC inputs of inverters. They ...

Melexis has come out with a 24V/60W sensorless single-coil BLDC driver designed for motor, fan and pump applications for both consumer and industrial electronics. At present, many consumer and ...

This article discusses a sensorless technique to control Brushless Direct Current (BLDC) motors using a majority filter implemented on a Digital Signal Controller (DSC). The algorithm utilizes a ...

Researchers at the Dubai Electricity and Water Authority (DEWA) R&D Center have developed a novel sensorless self-thermometry approach to estimate PV module operating temperature. Dubbed the ...

I have observed that humans are generally underdamped creatures. When excited with a step function change, we often overreact before settling in to a proper response. In the 90’s, the step function ...
