Title:
CAPACITIVELY COUPLED POWER SUPPLY
Document Type and Number:
WIPO Patent Application WO2004038902
Kind Code:
A3
Abstract:
A power supply comprises a pair of first and second capacitors forming a capacitive voltage divider. A source of a periodic input supply voltage is coupled to the capacitive voltage divider for producing in the second capacitor, from a portion of the periodic input supply voltage, a second supply voltage that is coupled to a load circuit. A switch is coupled to the second capacitor for selectively coupling the first capacitor to the second capacitor in a manner to regulate the second supply voltage.
