A full bridge inverter has bi-directional switches employed in a manner that their switching sequence produces a square wave voltage across a series R-L load. If the switching frequency is 50 Hz, Vs = 100V, R = 10 Ω and L = 25 mH, then the RMS value of the fundamental component of load current is:
1
90.07 A
2
31.47 A
3
7.08 A
4
15.73 A
