Power converters: Sinusoidal PWM

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

5.2. Sinusoidal PWM

Maximum of the 1^st harmonic

$U_{A0}(1)$ : U_dc/2=400/2=200 V (rms value 141 V)
$U_{zA}(1)$ : U_dc/2=400/2=200 V (rms value 141 V)
$U_{AB}(1)$ : U_dc/2 √3=400/2 √3=346 V (rms value 245 V)
