Q$1([32$ pts$)$: Choose the correct answer

The output voltage of three$-$phase full bridge $""$ control inverter varies from

a$)2V\frac{s}{3}$ to zero

b$)2V\frac{s}{3}$ to $-2V\frac{s}{3}$

c$)V\frac{s}{2}$ to zero

d$)-V\frac{s}{2}$ to $V\frac{s}{2}$

The fundamental component of output voltage for a half bridge inverter is given by

a$)(4\frac{V}{})sint$

b$)(2V\frac{s}{})sint$

c$)(V\frac{s}{2})sint$

d$)(Vs)sin2t$

A single$-$phase half bridge inverter has load $R=2$ and a dc voltage source $V\frac{s}{2}=115V.$ Find the rms value of the fundamental load current.

c$)86$ A

a$)51\mathrm{.}7$ A

b$)10\mathrm{.}25$ A
