VARIABLE FREQUENCY DRIVES MEGAWATTS – ELECTRICAL

Full DC variable frequency inverter

Full DC variable frequency inverter

DC to Variable AC Conversion: Converts DC power back into AC with adjustable frequency (0–250 Hz). Operation Benefits: Rated motor torque is available at low speeds. Starting current is significantly reduced, typically between 0.5 and 1.5 times the rated current. [pdf]
