“…Considering the aforementioned, several nonlinear control schemes have been proposed in the literature in the last two decades in order to obtain the desired benefits of the topology, which include power factor correction, harmonic compensation, and, as an extended property, voltage sag ride through [16][17][18][19][20][21][22], in spite of the fact that these techniques are as old as feedback control [23].…”

The requirements of PWM rectifiers for delivering power to motor drives include power factor correction and output voltage regulation even when strong variations such as voltage sags and dynamic load transients occur simultaneously. To achieve these objectives, the classic approach is to use a two-loop controller with its -model. In this paper, the authors propose a simplified approach to address that problem by using a feedback linearization-based nonlinear controller using only a single-loop current control and avoiding -modeling to reduce processing stages. To demonstrate the feasibility of this approach, several simulations are presented considering a 1.5 kW PWM rectifier.

“…In the case of voltage sags, their distinctive non-rectangular shape arises from the increased starting current of motors. Previous works have primarily focused on characterising and identifying sags using the space vector approach [1]- [4]. Intriguingly, a recent study employed a 3-D polarisation ellipse parameter for sag quantification [5].…”

This study employs differential geometric algebra to offer a fresh perspective on voltage sag and swell analysis. By utilising differential geometry, simulated electrical signals can be visualised as curves. This is made possible by describing the instantaneous amplitude of a sinusoidal wave as a curve in Euclidean coordinates. This approach effectively represents the Frenet-Serret frame rotation at each point along the curve. In systems with derivative components, the velocity of the moving frame denotes the rate at which events change, as the Frenet structure is locally defined at every point along the curve. This mathematical representation, utilising the Frenet frame, enhances our understanding of phenomena such as sag and swell, in contrast to traditional approaches that rely on the Clark and Park transformations, which utilise two-dimensional forms to capture the details and portrayal of an occurrence. The work emphasises the depiction of voltage through curves and provides a geometric indicator of the pattern’s evolution during operation.
