Power converters

5. Output voltage of three-phase inverters

5.1. Basic variables

Output voltage

$U_{A0}$ phase voltage of the inverter
$U_{zA}$ phase voltage of the load
$U_{AB}$ phase-phase voltage

For the 1^st harmonic component:

$U_{A0}(1) = U_{zA}(1)$ … viz KEV/PVE2
$U_{AB}(1) = √3U_{A0}(1) = √3U_{zA}(1)$

Example

Battery voltage \ (U_ {dc} = 400 V \), what is the available voltage on the motor?
