The figure below shows a half-bridge voltage source inverter supplying an RL-load with R=40 Ω and L=(0.3/π)H. The desired fundamental frequency of the load voltage is 50 Hz. The switch control signals of the converter are generated using sinusoidal pulse width modulation with modulation index, M=0.6. At 50 Hz, the RL-load draws an active power of 1.44 kW. The value of DC source voltage VDC in volts is
A
300√2
B
500
C
500√2
D
1000√2

Correct : c
