Role of Distriduted Converters in Solar Power Management

Y.Jhansirani , S.Mallikarjunaiah

The process of generation of electrical energy by the concept of power management with the presence of solar photovoltaic systems. Several new soft –switching technologies has been introduced. Taking into consideration as to improve energy capture resonant switched capacitor converters has taken, for voltage balancing modules. These are configured in parallel with strings of PV cells. The voltage balancing circuit transfers electrical charge between capacitor modules with soft switching operation reduction of power loss and EMI. These are configured in sub module level to improve energy capture even in the presence of shading or any mismatch occurs. This performs parallel ladder architecture that allows converter to handle only mismatch power and turn off if there is no mismatch that leads to optimize the maximum power from the PV system with higher conversion efficiency for a short circuit current mismatch gradient up to 40%.Since the circuit eliminates large magnetic components ,space requirement is less that is vertical foot-print less than 6mm and cost is low, reliability is high, insertion losses are less, and so complexity is less in the array.
