A patent application exposes that Apple is examining solar power converters to solve the problem of using bulky external converters in its devices
According to Apple Balla, the U.S. Patent and Trademark Office publishes an Apple patent application, which reveals about the tech giant’s endeavor of applying solar power converter in its different devices.
The integrated power management system includes a system micro controller (SMC) and a charger. The power can go through either an AC-to-DC adapter or the photovoltaic cell of the solar panel. The charger’s power stages are connected with the step-down-DC-to-DC converters. A charger IC investigates the incoming power, convert it into an appropriate voltage and process it either into an input current loop, a battery current loop, an output voltage loop or an input voltage loop for controlling the charging procedure.
The solar power converters will be very useful for portable devices, as it will provide them not only with the enhanced power facility but also remove the necessity of using bulky external converters.
