The following points should be noted when making power supply with capacitor voltage reduction:
（1）Capacitor voltage is better above 630V, and apply non-polar capacitors, polarity capacitors can not be used.
（2）Shunt the discharge resistance of the 500K-1M at both ends of the capacitor.
（3）In the process of assembling and debugging, the 1:1 isolation transformer should be used to connect to the AC220V circuit to prevent electric shock.
