The subsystem consists of three areas as shown in figure 2.

• The blue area (Inverter Control) enables the PWM signals (Enable Inverters) of the inverter module, sets it switching frequency (Inverters Switching Frequency), and adjusts its modulation index (Inverter modulation amplitude)

• The gray area (Signal Monitoring) is the block for receiving and monitoring data from the OPAL-RT simulator

• The orange area also provides important information regarding the test instructions

This subsystem consists of three main areas, including “OP8219 and OP8662 IO Interface,” “SIMULATION MODEL BASED ON MATLAB’S ‘UNIVERSAL BRIDGE’ BLOCK,” and “SIMULATION MODEL BASED ON ‘RT-LAB 2-LEVEL TSB’ BLOCK” as shown in figure 3.

• The orange area is used to interface the PWMs besides the voltage and current measurements.

• The blue andyellow areas are respectively used to implement the model in MATLAB and the real-time simulator.

• Both real time and MATLAB models are compared with the results measured from the test bench.

• Ensure that all power source outputs are off

• Connect the system power circuit and connection signals as shown in figure 4 -to 6

• Launch RT-LAB

• Import model zip file (see below) in RT-LAB

• Build, load, and execute the model

• Power on the OPAL-RT OP8662
