EXERCISE 2: Closed-Loop Controller Design and Simulation of H-bridge DC/AC Inverter with PV Objectives: - Getting familiar how a PV source operates when interfaced with an H-bridge PV Inverter Author: Babak

Parkhideh, PhD You need to take the "PV Array" block from the Simulink Library. Choose the SolarWorld Sunmodule Plus SW 250 mono Black from the Module data drop-down list. We use only one panel throughout the lab. First, consider the nominal operating points defined in the PV panel datasheet (mentioned in the Simulink interface too). Use the nominal parameters you have chosen in Exercise 1. You need to consider a DC link capacitor in parallel to the PV panel. Make sure the DC link voltage ripple in less than 2V at the nominal operating point. Construct the closed-loop feedback simulation model of the inverter interfacing with the PV array. If you have constructed the model in the previous labs, update the model. You can use the architecture shown below. Use the PID block in Simulink. Choose a proper Time Domain you have worked with, Continuous vs. Discrete. + Note that the modulation index must be sinusoidal to generate a 60Hz output. Make sure the compensator output is multiplied by Sin(2pi60t). Or, use the dq transformation or similar to extract the rms or mean value of the current. Multiply the current controller output by Sin(2pi60t).
