Learn more WhatsAppThis type of power supply is called a Class 1 power supply. In general, Y1-type capacitors are used in Class 2 equipment while Y2-type capacitors are used in Class 1 equipment. However, this might increase susceptibility to high-frequency common-mode noise, as discussed in this article .
Learn more WhatsAppA capacitive power supply usually has a rectifier and filter to generate a direct current from the reduced alternating voltage. Such a supply comprises a capacitor, C1 whose reactance limits the current flowing through the rectifier bridge D1.A resistor, R1, connected in series with it protects against voltage spikes during switching operations.
