220V RMS is more like 300V Peak

230V RMS ==325V Peak

@pproca, Missing bleeding resistor across capacitor. The inrush resistor with 1Ω is to low, better 1kOhm. @niko_20010, the formula for sinewave 220VAC * √2 = 220VAC * 1.414 = 311Vpeak

i know the conversion factor

I typically use about 100R as inrush limiter

Watching that waveform, my brain "hears" (synesthesia) "Wee-woo-wee-woo-wee-woo.."
