Question
A three-phase Voltage Source Inverter (VSI) as shown in the figure is feeding a delta connected resistive load of . If it is fed from a battery, with conduction of solid-state devices, the power consumed by the load, in kW, is __________.
Correct answer
23 to 25
Solution
For a three-phase VSI in conduction mode, the RMS value of the line-to-line output voltage is given by:Given ,The load is delta-connected with resistance per phase. In a delta connection, the phase voltage is equal to the line voltage:The total power consumed by the three-phase resistive load is:Thus, the power consumed is .
