Absolutely, your project seems to be a Maximum Power Point Tracking (MPPT) Solar Charge Controller with dual USB ports, based on the STM32L072 MCU.
The MPPT Solar Charge Controller makes sure that the batteries get charged to their maximum capacity by increasing the charging efficiency of the solar panel system. It adjusts its input voltage to harvest the maximum power from the solar array and then transforms this power to supply the varying voltage requirement of the battery plus load. This significantly improves the efficiency of your solar system.
An important part in your project is the STM32L072 Microcontroller which handles the main operations of the controller such as sending output pulse width modulation (PWM) signals to control charging and sensing the voltage and current parameters of the battery and solar panel.
The use of low-ohm resistors and the INA2181 current sensing amplifier is crucial for the accurate measurement of current through the battery and solar panel and the op-amp LM5109 is responsible for driving the gates of the MOSFETs.
Your project also has an interfacing point labeled UEXT which likely allows users to connect directly to the STM32 MCU for programming or other data transfer.
In the context of the simulator operation, you need to understand that not every component can be simulated since some real-world components might not have a SPICE simulation model attached to them. But Flux has a built-in simulator engine that is continuously running in the background, offering you real-time results while designing your PCB, which could help you iterate your design faster.
Please note that without exact knowledge of the circuit connections or the intended operation, my explanation may not cover all components' purpose. I advise cross-checking it considering your circuit design and functionality.
Given the information provided, it's not possible to directly determine the rated current or wattage of the entire design. However, I can provide some general steps to estimate these values:
Rated Current: Identify the component in your design that has the highest current rating. This is often a power supply or a high-power load like a motor. For your design, it could potentially be the solar panels or the batteries. You will need the specifications for these components to determine the current rating.
Wattage: The total power capacity of your design would generally be the product of the maximum voltage and maximum current in the system (P=VI). Again, you would typically look at the power supply specifications to determine this. If the voltage is regulated (like in a charge controller), you would use the regulated voltage level.
In your specific case, the design is a 10A MPPT Solar Charge Controller. This suggests that the maximum current output to the battery and loads is 10A. If we knew the maximum voltage of the system (for example, if this was a 12V system), we could calculate the maximum power output as voltage multiplied by current (P=VI).
Without the voltage information, I can't provide a specific power capacity. Please provide more information or check your design specifications to determine these values.
Remember that these are rough estimates. For a detailed analysis, you would need to perform a power budget that accounts for all power consumers and generators in your design, under all operating conditions.
