By analyzing the basic principle of voltage space vector PWM (SVPWM) and the AC electronic load which consists of voltage source PWM rectifier, a novel current control method is proposed. The control strategy combining the SVPWM and hysteresis current control technology is adopted. The vector of current error or the vector of differential of current error is used to select the most suitable voltage...
In this paper, a new control strategy based on current mode control for dynamic voltage restorer (DVR) is proposed to mitigate the power quality problems in the supply voltage. The DVR is controlled indirectly by controlling the supply current. The reference supply currents are estimated using the sensed load terminal voltages and the dc bus voltage of DVR. The control scheme is based on synchronous...
