A 3-phase inverter delivers power to a resistive load from a DC source 'VS'. For star connected load of 'R' Ω per phase, the RMS value of load current (Ior) for 180 degree conduction mode is _______.
1
\({I_{or}} = \frac{{\sqrt 2 }}{3}\left( {\frac{{{V_s}}}{R}} \right)\)
2
\({I_{or}} = \frac{1}{{\sqrt 2 }}\left( {\frac{{{V_s}}}{R}} \right)\)
3
\({I_{or}} = \frac{1}{3}\left( {\frac{{{V_s}}}{R}} \right)\)
4
\({I_{or}} = \frac{1}{{3\sqrt 2 }}\left( {\frac{{{V_s}}}{R}} \right)\)
5
\({I_{or}} = \frac{3}{{\sqrt 2 }}\left( {\frac{{{V_s}}}{R}} \right)\)
