Power converters: Voltage increase by zero-sequence component - example

Power semiconductor converters for vehicles with electric or hybrid drive. Traction inverters for supplying the electric motor from the traction battery.

5. Output voltage of three-phase inverters

5.5. Voltage increase by zero-sequence component - example

Maximum output voltage – SVPWM a TIPWM

Hexagon inscribed circle:

$\frac{2}{3}U_{dc}cos⁡(\frac{\pi}{6}) = \frac{2}{3}400\frac{\sqrt{3}}{2} = 231 V$

$U_{A0}(1)$ : 231 V, 163 V_rms
$U_{zA}(1)$ : 231 V, 163 V_rms
$U_{AB}(1)$ : 400 V, 283 V_rms
