A single phase half bridge inverter has RLC load. The dc input voltage (Vs/2) = 115 V and the output frequency is 50 Hz. The expression for the load voltage up to the fifth harmonic will be given by Correct Answer 146 sin 314t + 48.81 sin (3 x 314t) + 29.28 sin (5 x 318t)

In a single phase HALF bridge inverter only odd harmonics are present. i.e. 1,3,5 etc. Vo = (2Vs/π) sin ωt + (2Vs/3π) sin 3ωt + (2Vs/5π) sin 5ωt . . . (2Vs/π) = 146 V ωt = 2 x f x π x t = 2 x 3.14 x 50 x t = 314t.
