Overview

Solar power systems (solar power generation devices), being devices that produce sustainable energy, are representative eco-friendly systems, the use of which has spread from not only feed systems for private power generation in factories and so on, to power generation in homes.
Renesas provides optimal solutions for solar power generation devices. A varied lineup of microcontrollers, such as the RX24T Group and RX63T Group are available for building a system. High-efficiency semiconductor power devices (IGBT, MOSFET) are also available. These products enable Maximum Power Point Tracking (MPPT), an important function for solar power systems, to be handled by step-up voltage control. Moreover, through full digital control of system interconnection by inverter control, all power conversion is controlled by microcontroller, so fewer parts are required compared to an analog method and costs can be reduced. Control also has increased stability, making it highly suitable for solar power generation devices.
