The figure below shows a half-bridge voltage source inverter supplying an RL-load with R = 40 Ω and $\mathit{L}=\left(\frac{0.3}{\mathit{\pi }}\right)\mathit{H}$. 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 V_DC in volts is
