Question

In a $3 - ϕ$ inverter circuit shown in the figure, the load is balanced and the inverter is operating in $180^{\circ}$ conduction mode. All the devices are assumed to be ideal. If the DC bus voltage $V_{S} = 300 V$ , then the power consumed by the three phase load is ________.

Open in App

Solution

Line voltage, $V_{L} = \sqrt{\frac{2}{3}} \times V_{s} = \sqrt{\frac{2}{3}} \times 300$

$= 244.94 V$

Phase voltage, $V_{p h} = \frac{V_{L}}{\sqrt{3}} = \frac{244.94}{\sqrt{3}} = 141.42 V$

Power consumed by $3 - ϕ$ load

$P = \frac{3 V_{p h}^{2}}{R} = \frac{3 \times (141.42)^{2}}{20} = 3 k W$
