The DC voltage represents the voltage generated by an array of solar cells, with the following features:

$-$ Vdc $=110$V

$-$ Maximum power capacity : $1000$W

$-\backslash (\backslash$mathrm$\{$Vac$\}=120\backslash$mathrm$\{$Vrms$\}\backslash )$

$-\backslash (\backslash$mathrm$\{$R$\}=0\mathrm{.}5\backslash )$ ohms

$-$ L : large enough to have a very small ripple, so load consumes DC

Which is the delay angle such the maximum power is supplied to the AC side?

Which is the power received by the AC side?

Which are the losses?
