SOLAR CHARGING SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18591827 titled 'SOLAR CHARGING SYSTEM
The abstract of the patent application describes a solar charging system that includes a tandem solar cell and control unit with measuring circuit and storage device to control DC-DC converters based on command values.
- The solar charging system utilizes maximum power point tracking to determine the first command value for the first DC-DC converter.
- The relationship between the first command value and the second command value is defined by data stored in the storage device.
- The second command value for the second DC-DC converter is determined based on the first command value and the stored data.
- The system measures voltage and current of power input to optimize the charging process.
- The innovation aims to improve the efficiency and performance of solar charging systems.
Potential Applications: - Residential solar power systems - Portable solar chargers for electronic devices - Solar-powered outdoor lighting systems
Problems Solved: - Maximizing power output from solar panels - Efficient energy conversion in solar charging systems

Original Abstract Submitted
A solar charging system includes a solar panel including a tandem solar cell. A control unit includes a measuring circuit that measures a voltage and a current of power input to the first DC-DC converter. A storage device stores data defining a relationship between a first command value and a second command value. The solar charging system controls the first DC-DC converter according to the first command value and controls the second DC-DC converter according to the second command value. The first command value is determined by executing maximum power point tracking while measuring a voltage and a current. The second command value is determined by using the data stored in the storage device and based on the first command value.
