Ausführliche Berechnung des Effektivwertes?

Leider finde ich nirgends ein Rechenbeispiel um den Effektivwert bei so einer “Rechtecksspannung” zu berechnen. Brauch ich hier überhaupt das Integral zur Berechnung?

Auch würde ich gerne wissen ob meine bisherigen Ergebnisse aus 1.1 | 1.2 | 1.3 korrekt sind.

1.1 Nein, da Gleichwert != 0 [er ist -2]

1.2 Einweggleichwert = 800 V/S [(4V+12V)/0,02S]

1.3 Gleichrichtwert = 1700 V/S [34V / 0,02S]

The effective voltage is practically the average voltage.

That’s why PWM works so well because the an/off ratio is proportional to the effective value.

So simply remove the sign and image the average of values.

Where did you get the 34V? There’s only a maximum of 6V on it.

  • Disposable alignment means leaving all negative values away
  • Equivalent value is the mean value of the amount
  • Effective value is the square mean.

one must form the square average

You are forming the squares of the voltage values and forming the mean value.

This is then the square of the effective value:
