Step down DC power supply transformer less

Circuit elements:
Capacitor C1 470 uF .. Voltage 25 volts

Capacitor C2 470 nF .. Voltage 400 V

12-volt diode Wyzner .. Or no effort to choose

Diode Bridge Rectifier 1 Amp 300 v

Important notes ..
- Be careful with such a circuit because it is directly related with the source

- Stream of this department within the 100 mg volts .. And can be increased to increase capacitance C2
