    hey guys, a have a problem, and i dont seem to be getting anywhere near to an answer, so pls help here:

    A three-phase half-wave rectifier is feeding power to a highly inductive load. It has a
    supply voltage of 150 V/phase. Determine the mean load voltage and the required
    diode rating, assuming the load current is level at 25A. Assume each diode has a voltage drop
    of 0.7 V.

    I think the mean load voltage would be \left( V_{peak}-2\cdot 0.7 \right) \cdot \frac1{\frac{2\pi}{3}} \int_{-\frac{\pi}{3}}^{\frac{\pi}{3}} cos(\phi) d\phi

    Someone correct me if I 'm wrong.
