Three phase inverter control using DSP controller for dynamic voltage restorer (DVR) application
This paper discusses the control technique improvement of a three-phase inverter using directquadrature- zero (d-q-0) controller based on DSP TMS320F2812 for dynamic voltage restorer (DVR) applications. The output of the inverter is then connected to a voltage grid via a second order filter and i...

| Summary: | This paper discusses the control technique improvement of a three-phase inverter using directquadrature-
zero (d-q-0) controller based on DSP TMS320F2812 for dynamic voltage restorer (DVR)
applications. The output of the inverter is then connected to a voltage grid via a second order filter and
injection transformer. The control algorithms are developed using TMS320F 2812 DSP. The proposed
technique achieves voltage regulation with low total harmonics distortion (THD) for both voltage and
current. This paper also highlights a series of discussion, analysis and studies performed on the
proposed control technique, including L-C filter design issue and the concept of DVR in the distribution
system. An analysis and experimental results validate the effectiveness of the DSP controller in
mitigating voltage sags and harmonics issues in the distribution system |
