A power simulation was built with some power level components based on RT-LAB using the three level brushless alternator as simulation object. This simulation model combine RT-LAB and controllable power source. The controllable power source was controlled by the output of RT-LAB generator model, and used the output as a feedback to the system. Thus the model completed a power level closed-loop feedback simulation.
