This paper presents an active current detection method (ACDM) for three‐phase grid‐tied solar photovoltaic (PV) system. The proposed control utilizes the character triangular function (CTF) for fundamental component extraction and minimizes the computational burden. This shows the effectiveness of proposed ACDM under variety of operating conditions. Moreover, the design of control algorithm allows superior voltage regulation in outer voltage control loop, which reduces the peak overshoot during transients. This will also help in regulating grid current quickly, and it accurately follows the reference current. Further, the proposed control algorithm effectively deals with several power quality (PQ) issues and maintains the continuous power flow to satisfy the load demand. Finally, the withstand capability of the proposed ACDM controller is verified by simulation studies under MATLAB®/Simulink environment and experimentally validated by dSPACE‐1104 based downscaled laboratory prototype.
