The project was built and designed to measure the quality of AC voltage using a harmonic distortion meter based on PIC18F2550. The project was built and designed to measure the quality of AC voltage ...

Common to any production operation is movement, usually driven by electric motors. Better control of this movement contributes to improved operational performance. Beyond performance, however, there's ...

AC motors are abundant in the HVAC industry. Every fan and pump application requires an AC motor. For efficient and reliable control, adjustable-speed drives are becoming a common companion for these ...

The study of harmonics is expansive. Although the theory has been well established, the effects on the electrical system are still being discovered. Lately, this has been the case with high order ...

Designing total-harmonic-distortion (THD) measurement into a system usually involves a notch filter and a broadband ac measurement. The problem with this technique is that it measures both THD and ...

Pioneer Electric&Research has introduced a hardened digital multimeter featuring total harmonic distortion measuring on AC voltages. The Model PDM-550 has been designed for flight-line maintenance ...

A detailed analysis of the total harmonic distortion for a nonisolated boost topology with average current-mode control using the UC1854A and the UCC3817. IAC = Current reference. Ideally, IAC is a ...
