摘要： An embodiment of a method includes generating a regulated output signal from a regulated intermediate signal in response to a reference signal and the regulated output signal, and generating the regulated intermediate signal from an input signal in response to the regulated output signal and the regulated intermediate signal. By generating one regulated signal (e.g., a regulated output voltage) from another regulated signal (e.g., a regulated intermediate voltage), the magnitude of the ripple component of the one regulated signal may be reduced. Furthermore, by generating the regulated intermediate signal in response to the regulated output signal, the efficiency of the regulation may be increased.

摘要： Apparatus for regulating a d.c. voltage appearing across a load. The emitter-collector junction of a transistor is connected in series with a retardation coil and with the load impedance to a d.c. voltage source. The voltage applied to the load impedance is compared with a reference voltage in a regulating circuit. The latter circuit provides an output signal of a value which is a function of the d.c. voltage appearing across the load impedance. The conductivity of the emitter-collector path of the aforementioned transistor is controlled by the latter output signal. An adjustable impedance is connected in series with the primary winding of a transformer and to the voltage source. The secondary winding of the transformer is connected across the base-emitter junction of the aforementioned transistor, and the signal appearing across this winding controls the operation of the transistor. A frequency generator produces a timing signal, which through the regulating circuit, produces an edge of the output signal. The other edge of the output signal is a function of the d.c. voltage appearing across the load impedance.

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.
