Design Of An Intelligent Controller For An Active Filter (1992)
AuthorsDuke, R.M., Round, S.D.show all
A technique of achieving both active current distortion compensation and power factor correction is briefly described. The active filter has been evaluated using a single phase prototype circuit that provides up to 2 kVA of distortion compensation. There is an optimum operating range for the active filter which is determined by the choice of average switching frequency and inverter DC bus voltage. Experimental results, illustrate the filter's ability to reduce the current harmonic distortion components, are presented On the basis of these experimental results, the design of an intelligent controller, using a Texas Instruments TMS32OC30 Digital Signal Processor (DSP), for the active filter is proposed. Such an intelligent controller should be able to determine the most eficient average switching frequency and inverter DC bus voltage to achieve the required current distortion compensation and/or power factor correction.
