Optimal control of a three phase boost rectifier for unity power factor and reduced harmonics
1995
A vector controlled motor drive system consisting of a boost rectifier, inverter and induction motor is considered with emphasis placed on the rectifier side. Boost rectifiers can supply DC power while maintaining a sinusoidal AC current with an arbitrary value of fundamental power factor. They are required to simultaneously control both the DC voltage and the reactive current. A DSP-based discrete-time integral-type optimal regulator is considered for the control because it can provide a robust control system and can accommodate for the computational delay in the output. To obtain higher control performance, a DC load current feedforward signal from the inverter side is added. >
