SPV1020 Datasheet PDF - ST Microelectronics

●The SPV1020 is a monolithic 4-phase interleaved DC-DC Boost Converter designed to maximize the power generated by photovoltaic panels independent of temperature and amount of solar radiation. Optimization of the power conversion is obtained with embedded logic which performs the MPPT (max. power point tracking) algorithm on the PV cells connected to the converter. One or more converters can be housed in the connection box of the PV panels, replacing the bypass diodes. As the maximum power point is locally computed, the efficiency at system level is higher than that of conventional topologies, where the MPP is computed in the main centralized inverter. It operates at fixed frequency in PWM mode, where the duty cycle is controlled by the embedded logic running a Perturb&Observe MPPT algorithm.
