Abstract
PURPOSE: When driving many AC motors by one rectifier through many inverters, to improve control performance by providing main voltage regulating function in the rectifier fine regulating function in the inverter.
CONSTITUTION: When converting AC power through thyristor rectifier 121 to DC power then converting through each inverter 157-187 to AC power having predetermined frequency to drive induction motors 152-182, inverters 157-187 have frequency control function and fine voltage control function and most of voltage control is performed by rectifier 121 while fine voltage regulation is performed by each inverter. Consequently approximately same control performance is achieved fine regulating function even for motors having slightly different characteristic, thereby acceleration/deceleration can be executed simultaneously with high efficiency.
