N2 - This paper introduces a dynamic-gain MPPT algorithm for PV systems. The method demonstrates a rapid and uniform convergence toward the MPP by employing dynamic steps while owning MPPT control compatibility even for differential power processors. A theoretical analysis on the effects of resolution on limit cycle oscillations existence and power curve traps in the MPPT process is provided. The dynamic gain MPPT algorithm is demonstrated by simulation and experiments, avoiding limit cycle oscillations and power curve traps. The presented algorithm is verified on bi-directional differential power processors, demonstrating dynamic MPP convergence with no limit cycle oscillations and significant improvement of power harvesting capability up to 42%.
