Hardware realization of a 10KVA hybrid active power filter

This paper presents a hardware realization of a LC coupled hybrid active power filter (LC-HAPF). According to the characteristics of the load, the corresponding passive part of the LC-HAPF and the reference dc-link voltage can be designed, under the requirement of IGBT and the digital signal processor (DSP), the IGBT driver and the signal condition board for the DSP can be designed too. Finally, based on the design, the compensation control algorithm for the LC-HAPF can be implemented by the DSP, and all the compensation results satisfied the international standars.
