Abstract
A converter circuit includes first and second input terminals, control circuitry, and a storage capacitor. The first and second input terminals are configured for connection to an AC power supply to receive an AC signal. The control circuitry is coupled to the first and second input terminals. A terminal of the storage capacitor is coupled to an output node of the control circuitry. The storage capacitor is charged by the control circuitry and configured for use as a DC power source. The control circuitry is configured to couple the first input terminal to the storage capacitor during a portion of a positive half-cycle of the input AC signal to charge the storage capacitor and to decouple the first input terminal from the storage capacitor during an entirety of each negative half-cycle of the input AC signal, to thereby prevent discharging of the storage capacitor by the input AC signal.
