A three-phase voltage source inverter with ideal devices operating in $180^{\circ}$ conduction mode is feeding a balanced star-connected resistive load. The $DC$ voltage input is $V_{dc}$. The peak of the fundamental component of the phase voltage is
- $\frac{V_{dc}}{\pi} \\$
- $\frac{2V_{dc}}{\pi} \\$
- $\frac{3V_{dc}}{\pi} \\$
- $\frac{4V_{dc}}{\pi} $
