NOVEL PWM TECHNIQUE MINIMIZING THE PEAK INVERTER CURRENT AT STEADY-STATE AND TRANSIENT OPERATION
暂无分享,去创建一个
For the control of PWM inverters optimal pulse patterns are defined with the objective of minimizing the peak inverter current. Special attention is given to three-state inverters as applied to high power ac motor traction drives. The optimization relates to steady-state and transient operating conditions. Experimental results are illustrated by oscillograms.
