Abstract
A novel converter topology with a high-boost voltage gain for photovoltaic (PV) applications is proposed in this work. An unique converter-inverter drive system is used, where the topology is based on a switched-capacitor based dual switch (SCDS) dc-dc converter and a three phase voltage source inverter (VSI). The typical topology of SCDS converter has properties like high gain, reduced voltage stress and reduced loss on the power devices. The output of the converter system which is fed directly from PV energy, is given to the inverter system in which SPWM control is used. MPPT control is utilized to achieve utmost power output from a photovoltaic module. The validity of the presented system is verified by the MATLAB simulations. An output voltage of 200V is obtained from the SCDS converter for an input voltage of about 25V to 50V and is converted to an ac voltage of about 105V at the load side by the inverter.
