EXERCISE 1: Closed-Loop Controller Design and Simulation of H-bridge

DC/AC Inverter

Use Matlab/Simulink. You can use SimPower or Simscape libraries to simulate components needed

in power electronics.

Key elements that you need to simulate an H-bridge DC/AC Converter as shown in the figure above:

• Four Mosfets

•

One Inductor

One Capacitor

One Resistor

• DC Voltage Supply

PWM Generator

Other elements needed to run the simulation (not essential in the converter operation)
