| Abstract |
A novel control scheme for PWM rectifier-inverter
system is proposed. Fast control strategies such as line voltage
Sensorless Virtual Flux (VF) based Direct Power Control with
Space Vector Modulator (DPC-SVM) for rectifier and Direct
Torque Control with Space Vector Modulator (DTC-SVM) for
inverter side are used. These strategies lead to good dynamic
and static behaviour of the proposed control system – Direct
Power and Torque Control- Space Vector Modulated (DPTSVM).
Simulations and experiment results obtained show good
performance of the proposed system. Additional power
feedforward loop from motor to rectifier control side improved
dynamic behaviours of the power flow control. As a result, better
input-output energy matching allows decreasing the size of the
dc-link capacitor. |
