“…The MA filter approximation presented by [4], [5] is valid for slow PLL transient response design specifications, found in applications such as reference signals generation for a Dynamic Voltage Restorer (DVR) [6], [7]. For applications that require fast PLL transient response (settling time less than three cycles) the controller of [4], [5] does not provide satisfactory results, as the high frequency region of the MA filter transfer function is not adequately modeled with this low order simplified model.…”

-Phase Locked Loops using phase detector based on a multiplier and a moving average low pass filter are computationally simple, and provide adequate attenuation for the multiplier generated harmonics, which are responsible for distortion at the output signal. They are a good choice for synchronizing power electronics converters connected to the grid. Previously published papers based on proportional-integral control and moving average filter present long settling times. This paper uses the exact model of the moving average filter by its discrete high order transfer function, and applies the discrete root locus method to impose the dominant closed loop poles in a region defined by desired performance specification. It leads to a significantly shorter settling time, when experimentally compared with other recent proposals in the literature. 1

“…In recent years, a large number of nonlinear loads for high efficiency control are used, which seriously affect the quality of power energy, increase the harmonic content, and cause the distortion of voltage and current [1][2]. Nowadays, the power quality problem has been widely concerned, and especially it is of great significance to improve the power quality of the sensitive load in the distribution system.…”
