摘要: The best way to avoid MPPT drawbacks due mismatching phenomena is use a dedicated DC/DC converter, in charge of MPPT, for each PV panel instead big central converter the whole array. Dedicated converters can be boost-like converters; they must serially connected other obtain an higher voltage as required by grid inverter. However, when number panels relatively low, sum voltages boost string may insufficient allow inverter energy conversion function. In this paper non isolated interleaved switched inductance proposed and studied. Such characterized high ratio quite simple construction. A mathematical study static characteristics both CCM DCM conditions provided together with analytical estimation losses. Moreover, has been compared, terms losses, dual stage synchronous converter.
