Two-inputs, Two-outputs (TITO) active filter

Most active filters for electromagnetic compatibility (EMC) are designed as Single-Input Single-Output (SISO) systems. This work proposes an innovative approach with a control strategy for a Two-Inputs Two-Outputs (TITO) active filter. This model employs two detection points and two injection points, optimizing noise attenuation on power lines. Integrated into the regulation loop, it allows precise control of line currents without relying on the traditional separation of modes (common mode and differential mode), while inherently accounting for mode conversion phenomena. This approach offers a different method for active filter design.
