    Pulse Unit Vfd
AI Thread Summary
A 36 Pulse VFD unit offers significant advantages over a 12 Pulse unit, primarily in its ability to better approximate a sinusoidal wave. This increased pulse count results in lower harmonic distortion, which is crucial for improving overall system efficiency and reducing electrical noise. The cancellation of harmonics plays a vital role in the selection of pulse configurations, as higher pulse counts lead to enhanced performance. Ultimately, a 36 Pulse VFD is more effective in minimizing power quality issues. Choosing the right pulse configuration is essential for optimizing VFD performance.

Hi,

I would like to ask if anyone with VFD and PWM - Invertor knowledge could give me a run down on the advantages of a 36 Pulse VFD Unit in comparison to a 12 Pulse? Is the cancellation of harmonics a factor in Pulse selection?

Thankyou

The more pulses you have the better you can approximate the sinusoidal wave. And the more pulses you have the lower the harmonic distortion.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
