Hi,
Exactely. But only - as clearely writen - with capacitor.
A 230V AC sine with full wave rectifer:
..gives 325V DC, with unloaded capacitor. (= 325V RMS, 325V average)
..gives 230V AC RMS, without capacitor.
..gives something between 230V RMS and 325V RMS, with loaded capacitor.
A 230V AC sine with half wave rectifer:
..gives 325V DC, with unloaded capacitor. (= 325V RMS, 325V average)
..gives 162V AC RMS, without capacitor.
..gives something between 162V RMS and 325V RMS, with loaded capacitor.
A simulation can show you this.
