In architectures based on the use of power optimizers, the maximum power point tracking (MPPT) function is performed at the level of each photo-voltaic panel so they all operate at their maximum power point. This results in an improved energy yield of the overall solar system compared to traditional string or central inverter based architectures.

Power optimizers can help minimize a system’s design constraints as well as improve reliability and safety – by helping ensure compliance with the latest NEC 2017 regulations that require rapid shut-down in the event of grid disconnection, while at the same time reducing maintenance costs.

We provide high-performance STM32 microcontrollers as well as high-efficiency silicon-carbide, SiC MOSFETs and diodes, trench-gate field-stop IGBTs, galvanically-isolated gate drivers and Power Line communication solutions to help achieve superior efficiency and reliability for the implementation of power optimizer based architectures.
