This paper, the design and experimental implementation of a low cost and high efficiency photovoltaic system based on a new quasi-square wave resonant switch (QSW) dc-dc soft-switching buck converter operating in discontinuous conduction mode (DCM) that controlled by a maximum power point tracking (MPPT) was proposed. Due to the power switch of the converter in the proposed system was turned-on and turned-off by softswitching technique. The power circuit implementation in the proposed system is very simple and it was comparable with the conventional QSW converter because it required only one power switching device and one inductor coil. Analytical model was...
