Microcomputer-based control apparatus for a load-commutated inverter synchronous machine drive system

摘要: A load-commutated inverter synchronous machine drive system control apparatus comprises at least one microcomputer for determining optimum or desired values turn-off time, link current and air gap flux from voltage currents. Inverter frequency is regulated in accordance with the difference magnitude between actual time to minimize angle irrespective of frequency, thereby reducing reactive power. field are responsive flux, respectively, assuring operation maximum efficiency.
