<p>A high frequency electric driving device with a multi-pole motor for gas pipelines and storage compression applications is provided to prevent efficiency from being lowered by producing high quality multilevel voltage signals. A high frequency electric driving device(1) comprises a high frequency power converter, one or more multi-pole motors(12), and one or more single-stage or multi-stage centrifugal compressors(10). The high frequency power converter supplies electricity to one or more multi-pole motors. The high frequency power converter comprises a hybrid bridge. The hybrid bridge is composed of two levels in order to supply the electricity to one or more multi-pole motors. One or more multi-pole motors are provided with the electricity from the high frequency power converter. One or more single-stage or multi-stage centrifugal compressors are driven with one or more multi-pole motors.</p> |
