STEVAL-ISV009V1 Datasheet PDF - ST Microelectronics

●STEVAL-ISV009V1 demonstration board is based on SPV1020, which is a monolithic DC/DC boost converter designed to maximize the power generated by photovoltaic panels independent of temperature and amount of solar radiation. The 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 and, because 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 works at a fixed frequency in PWM mode, where the duty cycle is controlled by the embedded logic running a perturb & observe MPPT algorithm.
