Name: ID# Q.3 A unipolar PWM single-phase full-bridge DC/AC inverter has Va = 400V, ma = 0.8, and ftri = 1800 Hz. The inverter is used to feed RL load with R = 101 and L = 18mH at fundamental frequency is60 Hz. Determine: (12 marks) a) The rms value of the fundamental frequency load voltage and current? b) The highest current harmonic (one harmonic)? c) An additional inductor to be added so that the highest current harmonic is 10% of its in part b?
