In this simulation, we'll delve into the intricacies of the MBBT solar charger controller, specifically focusing on the MPPT (Maximum Power Point Tracking) and MBPT (Peak Power Tracking) functionalities. This controller plays a crucial role in optimizing power generation and battery charging in solar systems.

Understanding the MBBT Solar Charger Controller:

The MBBT solar charger controller comprises two key components – MPPT and MBPT. The MPPT block, when inspected closely, reveals its structure with input validation temperature parameters. This model utilizes inputs such as irradiation temperature to generate the V reference voltage and Peak power voltage.


How the System Works:

The controller's operation involves comparing the Peak Power Voltage with the PV voltage. A proportional-integral (PI) controller processes this comparison, generating the duty cycle. This duty cycle is regulated based on battery State of Charge (SOC) and fully charging voltage conditions.


Key Components and Specifications:

  1. PV Array: Comprising a single 250W power, 39.9V, and 8.1A at maximum power conditions.

  2. Configuration: Four series panels in each of the two parallel strings, allowing for a total potential generation of 2000W under specific conditions.

  3. Battery: A 40V, 200 Ah capacity battery is employed to store the generated power.

  4. Converter: The converter can operate in both buck and boost modes based on the duty cycle.


Simulation and Results:

The provided simulation demonstrates the system's response to changes in irradiation conditions. Starting with 1000W/m² and switching to 500W/m² after five seconds, the system maintains stability. The battery charging curve and PV power response showcase the efficient performance of the MBBT controller.


Comparison with MPPT:

The comparison with MPPT reveals that the MBBT controller exhibits a smoother response during transient conditions. There are minimal oscillations and smooth transitions in PV voltage and current, showcasing its superior performance in battery charging control.


Conclusion:

In conclusion, the MBBT solar charger controller with MPPT and MBPT proves to be a robust solution for efficient power management in solar systems. Its ability to adapt to changing irradiation conditions and regulate battery charging with minimal transient behavior makes it a valuable component in renewable energy setups.
