STMicroelectronics SPV1020 Interleaved
DC-DC Boost Converter

The STMicroelectronics SPV1020 Interleaved DC-DC Boost Converter is a monolithic device designed to maximize the power generated by photovoltaic panels independently of temperature and amount of solar radiation. The optimized of the power conversion is obtained with an embedded logic that performs that MPPT (maximum power point tracking) algorithm on the PV cells connected to the converter. One or more converters can be housed in the connection box of PV panels, replacing the bypass diodes. The maximum power point is locally computed, providing a higher efficiency at system level than one of the conventional topologies. The STMicroelectronics SPV1020 DC-DC Boost Converter embeds the power MOSFETs for active switches and synchronous rectification, minimizing the number of external devices. The switching frequency of the SPV1020 is internally generated, set by default at 100kHz, and is externally tunable. The duty cycle can range from 5% to 90% with a step of 0.2%.
