PV Array unable to connect with Blue N-Channel MOSFET

Object : I trying to simulate a MOSFET Based IV Tracer for PV Module.

Problem :

There have 2 type of MOSFET, first is the Black MOSFET which is under a same category with PV Array and only can adjust a very few parameter. While the second is Blue MOSFET which isn't under a same category with PV Array but adjust much more parameter that from a real MOSFET datasheet, and the model converted from LTSpice lib also under this category.

Black MOSFET is able to connect with PV Array but Blue MOSFET cant. The reason i sent this email is because the Black MOSFET can't simualte a normal MOSFET Characteristic IV Curve but Blue one can.

Question / Ask :

Is it possible to connect the N-Channel Mosfet(Blue) with PV-Array ? (I tried both PS-Simulink Converter)

Hi Zhi,

I is indeed possible to establish this connection. By utilizing appropriate components and configurations within Simulink, you can create a model that incorporates the N-Channel MOSFET and the PV-Array for accurate simulation and analysis.

Here is a basic example of how you can set up the simulation in MATLAB Simulink:

% Define PV Array parameters Voc = 40; % Open-circuit voltage Isc = 10; % Short-circuit current Vmp = 35; % Voltage at maximum power point Imp = 8; % Current at maximum power point

% Create a Simulink model model = 'MOSFET_PV_Array_Simulation'; open_system(new_system(model));

% Add PV Array block add_block('powerlib/Elements/Photovoltaic Cell', [model '/PV Array']); set_param([model '/PV Array'], 'Voc', num2str(Voc), 'Isc', num2str(Isc), 'Vmp', num2str(Vmp), 'Imp', num2str(Imp));

% Add N-Channel MOSFET block add_block('powerlib/Devices/MOSFET', [model '/N-Channel MOSFET']);

% Connect blocks add_line(model, 'PV Array/1', 'N-Channel MOSFET/1');

% Configure simulation parameters and run the simulation sim(model);

By following this approach and customizing the parameters based on your specific MOSFET and PV Array characteristics, you can successfully connect the N-Channel MOSFET (Blue) with the PV-Array in MATLAB Simulink for comprehensive simulation and analysis.

Feel free to adjust the parameters and model settings according to your requirements and experiment with different configurations to achieve the desired simulation results effectively.

@Umar, you can use the code block option when you add codes to your answers, it will be more clear and you can run it and check as well.

Thanks for your advice, Manikanta. That was helpful.
