摘要： A back-feed protection circuit includes input circuits and a control circuit. Each input circuit includes an input for receiving an input DC voltage. The control circuit is configured to enable one of the first input circuit and the second input circuit having the highest input DC voltage, and disable the other input circuit to substantially prevent current from back feeding to the first input circuit and/or the second input circuit. Each input circuit additionally and/or alternatively includes a positive rail, a reference rail and a plurality of switching devices. A set of the switching devices are coupled in series in the positive rail of each input circuit, and another set of the switching devices are coupled in series in the reference rail of each input circuit. Other example back-feed protection circuits, and electric power supplies including back-feed protection circuits are also disclosed.

摘要： A voltage step-up circuit, or booster circuit, wherein in response to a first signal a first switching element is enabled to charge a first capacitor with an input voltage while a second switching element is disabled, and in response to a second signal the second switching element is enabled to charge with the input voltage a second capacitor connected in series to the first capacitor while the first switching element is disabled. The sum of the voltages appearing across the first and second capacitors is derived as an output voltage. The "ON" and "OFF" times of the first and second signals may be varied, and the ratio between the "ON" time of the first signal to the "ON" time of the second signal may also be varied. The number of switching elements and capacitors may be increased as needed.
