App note: Solar-LED streetlight controller with 25 W LED lamp driver and 85 W battery charger based on the STM32F101Rx
A great app note from STMicroelectronics on Solar lighting application. The solar-LED streetlight controller described in this application note is designed to achieve an 85 W solar energy battery charger and a 25 W LED lamp driver. During the daytime the controller preserves the electricity energy gathered by the solar module (PV module), then stores […]
App Note: Grid-connected solar microinverter using a dsPIC® DSC
In this advanced app note Microchip details the theory behind converting solar energy into usable electric power. Starting with a discussion of the electrical characteristics of photovoltaic (PV) cells, they move onto the tech behind inverters and the mathematics involved with their proper design and use. Finally a microinverter reference design is presented, using a […]
