A 30kVA dynamic voltage restorer based on TMS320F2812 is proposed in order to solve the problem of voltage fluctuation for active distribution network. The power circuit, DSP circuit, voltage and current measurement circuit, PWM drive circuit and protection circuit are also designed. The intelligent power module PM300DVA120 and 6-channel, simultaneous sampling 16-bit A/D converter AD7656 are adopted to construst power circuit and measurement circuit respectively. The output voltage of DVR can be controlled in phase or opposite phase with the voltage-oriented control based on synchronous reference frame theory. The steady state and dynamic state experimental results are given at the 10 kHz switching frequency with 5μs dead time. The DVR system presented in this paper has good performance of dynamic and static response so as to be used for the active distribution network that has the voltage stability need.
