This paper presents a new implementation of flyback-type inverter to optimize power flow from solar PV (photovoltaic) system. The flyback-type inverter used is Shimizu topology. The main features of this inverter type include: extended lifetime of the inverter, providing small volume, lightweight, lower harmonic content and stable AC current injection into the load or utility line. Three controllers used comprise non-MPPT, conventional Incremental Conductance (IC) and IC+PID method. To verify the effectiveness of the inverter design, such methods are examined with different irradiance conditions. The results show that the Shimizu flyback-type inverter exhibits considerable optimum performance and can harvest a good maximum power under various irradiance condition. The results also indicate that the IC+PID method gives less harmonic distortion. © 2018, ICIC International. All right reserved.
