A capacitive power supply or capacitive dropper is a type of power supply that uses the capacitive reactance of a capacitor to reduce higher AC mains voltage to a lower DC voltage. It is a relatively inexpensive method compared to typical solutions using a transformer, however, a relatively large mains-voltage capacitor is.
