6 pulse diode VFD, weatherproof solution protects VFDs operating in outdoor locations. Cost effective high IP rating solution and wider temperature range from -30°C to +55°C.

The 12 pulse diode VFD, matched with a 12 pulse phase shifting transformer, is the most popular low-harmonic solution in ESP applications, and the input harmonic distortion is about 5% to 10%. It is also an outdoor-type VFD and can be used in harsh e....

The principle of the 24 pulse rectifier has two 12 pulse rectifiers in parallel with two three-winding transformers having a 15⁰ phase shift. The benefit is that practically all low frequency harmonics are eliminated and the harmonic distortion is le....
