A few years ago, [Lukas Fässler] needed a solar charge controller and made his own, which he has been improving ever since. The design is now mature, and the High Efficiency MPPT Solar Charger is full ...

A newly proposed inverter design relies on a solar charge controller featuring maximum power point tracking. It is based on an artificial fish-swarm algorithm, which offers high convergence speeds, ...

Infineon Technologies AG announced that BRC Solar GmbH has selected Infineon's CoolGaN Transistor 100V devices as the core switching technology for its Power Optimiser. The CoolGaN Transistor 100V ...

Few can question the increasing role of photovoltaic (PV) technology as a scalable, robust means of renewable energy. Yet PV cells are but one element, albeit a critical one, in an overall PV system.

Fig 1. The multiplierless MPPT system incorporates a buck converter and a control stage. R SHU and the current sense amplifier, U5, sense the system’s output power. Fig 2. Using a perturb-and-observe ...

This is a simple solar boost converter and voltage limiter circuit that charges a 12V battery from a 6V solar panel. It also demonstrates MPPT (Maximum Power Point Tracking) capability. When we think ...
