And I saw it is a so-called voltage divider using capacitors: Capacitive Voltage Divider as an AC Voltage Divider. And I thought to implement the following circuit: simulate this circuit – Schematic created using CircuitLab. Based upon the site, I find with a 10 µF capacitor and 220 V 50 Hz AC the voltage across C1 is 99 V and not 110 V.
Ripple voltage = Current draw / ( (Ripple frequency) * (Capacitor size) ) or written another way. Capacitor size = Current draw / ( (Ripple frequency) * (Ripple Voltage) ) For a half wave rectifier (single diode) the frequency is 60 Hz (or 50 Hz in europe). The current draw is how much current your project is going to need, maximum.

Voltage multipliers are similar in many ways to rectifiers in that they convert AC-to-DC voltages for use in many electrical and electronic circuit applications such ... But because there is a voltage across capacitor C1 already equal to the peak input voltage, capacitor C2 charges to twice the peak voltage value of the input signal. In other ...
Low-Pass Filter a PWM Signal into an Analog Voltage
This calls for always lower value of resistance in the filter, and also calls higher capacitor values to reach the pole frequency. The average voltage for 39% PWM in 5V is 5*0.39 = 1.95V. If FilterR = 1k and Load = 10k, the currente will be 1.95V / 11k = 1.77µA, voltage at output = 10k * 1.77µA = 1.77V instead of 1.95V.
