A New Solution for Harmonics Generated by VSDs

← Back to document page

A New Solution for HarmonicsGenerated by Variable Speed DrivesIn addition to its harmonic mit-igating capabilities, this widespectrum harmonic filter helpsprotect a VSD from transientovervoltages caused by capacitorswitching and other fast changingloads. It is suitable for virtuallyany application involving a VSDor similar 3-phase, 6-pulse diodebridge rectifier load. Harmonic ProblemsThe front-end diode bridge recti-fiers of 3-phase, 6-pulse static powerconvertors (ac-dc), such as those foundin variable speed drives, are considerednonlinear because they draw current ina non-sinusoidal manner.
