This paper presents micro-inverter to regulate power delivery from a small scale solar photovoltaics using a phasebased control technique. The micro-inverter used is a flyback-type inverter. Instead of controlling the voltage magnitude, the proposed control method uses power angle as control parameter to yield maximum power. The phase angle is obtained from Maximum Power Point Tracker (MPPT) algorithm and then employed as the phase reference for shifting the power angle of sinusoidal signal from phase-locked loop (PLL) block. Several simulation experiments are performed to examine the design. A conventional technique is also presented for comparison. The simulated data shows that the implementation of this phase-based flyback inverter exhibits satisfactory results and hence can be used as an alternative method. © 2020 Institut za Arhitekturu i Urbanizam Srbije.
