What is it about?
This article proposes a new control system for an active power filter based on a current source inverter (CSI), designed to reduce the impact of pulsed power loads on electrical grids. The CSI stores energy in a DC inductor and uses space vector modulation (SVPWM) to smooth out current peaks caused by loads that draw large bursts of power. Two coordinated controllers manage the AC grid currents and the DC energy storage. Simulation results show that this system can significantly improve power quality and maintain stable voltage, even in weak or isolated grids.

Why is it important?
Pulsed power loads, common in industrial and military applications, can cause serious voltage drops and instability in power systems. Traditional filtering solutions are not always effective or efficient. This work introduces a compact and energy-efficient way to actively filter these disturbances using a CSI with inductor-based storage. It offers a promising solution to improve voltage regulation and reduce the stress on distribution networks, especially in sensitive or remote applications.
Perspectives
This research stemmed from my interest in applying control strategies to real-world power quality challenges. By combining inverter-based control with innovative modulation techniques, we achieved a practical and scalable solution. For me, this work represents how advanced modelling, and simulation can support new architectures in power electronics with direct applications in smart grids and critical load management.
