CONSTITUTION:The frequency command from a speed setter 4 is converted into the pulse train having a frequency 6f six times as much as the inverter frequency with a voltage/frequency converter 6 and sent out to a ring counter 16. At a ROM 10, the optimum switching signal read out of an ...
Deadbeat control of PWM inverter with repetitive disturbance prediction A new approach for deadbeat control of a PWM invertor is presented, in which the estimation of the disturbance is carried out with a repetitive predictor i... Z Kai,Y Kang,X Jian,... - Applied Power Electronics Conference...
The power output and the dynamic performance of PWM (pulse width modulated) controlled AC motor drives can be improved by increasing the inverter output voltage through overmodulation. Two different solutions are proposed to increase the output voltage in a continuously controllable fashion up to maximu...
