Capacitive power supply
A 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.
