I have some questions about 3-phase rectifiers.

First of all:

1- At the load, the voltage we measure there is a

**Line Voltage**or a

**Phase Voltage**?

2 - Then we have derived the equations for the Load Vavg for Half and Full wave 3-phase rectifiers and I ended up writing this on my notes books:

__Half wave__

- Not controlled:

\[\displaystyle{VLoad_{avg} = \frac{3\cdot\sqrt{3}}{2\cdot \pi}\cdot Vmax }\]

- Controlled:

\[\displaystyle{VLoad_{avg} = \frac{3\cdot\sqrt{3}}{2\cdot \pi}\cdot Vmax \cdot \cos\left ( \alpha \right )}\]

__Full wave__

- Not controlled

\[\displaystyle{VLoad_{avg} = \frac{3\cdot\sqrt{3}}{\pi}\cdot Vmax }\]

- Controlled:

\[\displaystyle{VLoad_{avg} = \frac{3\cdot\sqrt{3}}{\pi}\cdot Vmax \cdot \cos\left ( \alpha \right )}\]

But when I read Mohan's Book

and I can't see the relationship between equation 6-36 and the ones I have from my notes book! I mean, why I have one expression in my notes book, and Mohan's book equations are different?
