摘要： A power supply apparatus includes first through M-th switching regulators, first through N-th multiplexers, and first through N-th linear regulators, where each of M and N is a natural number greater than or equal to two. The first through M-th switching regulators generate first through M-th reference power signals using an input power signal. The first through N-th multiplexers select one of the first through M-th reference power signals, in response to a power selection signal, to provide first through N-th selection power signals. The first through N-th linear regulators generate first through N-th output power signals using the first through N-th selection power signals. The first through N-th linear regulators are connected to the first through N-th multiplexers, respectively.

摘要： A converter control arrangement (18) for regulating the output current of a dc source power converter (16) comprises a current regulator (20) for regulating the output current based on a comparison of an output current value (Iout) of the dc source power converter (16) with a desired target current value (Itgt). When the output voltage value (Vout) of the dc source power converter (16) is within a normal operating voltage range between minimum and maximum voltage values (Vmin, Vmax) defined with respect to a voltage reference value (Vref) of the dc source power converter (16), the converter control arrangement (18) controls the target current value (Itgt) so that it is equal to a desired reference current value (Iref). When the output voltage value (Vout) is outside the normal operating voltage range, which typically indicates a fault condition, the converter control arrangement (18) modulates the reference current value (Iref) to provide a target current value (Itgt) that is less than the reference current value (Iref).

摘要： An electrical-energy harvesting system envisages a transducer for converting energy from an environmental energy source into a transduced signal, an electrical energy harvesting interface for receiving the transduced signal and for supplying a harvesting signal, and an energy storage element coupled to the electrical energy harvesting interface for receiving the harvesting signal. The electrical-energy harvesting system also includes a voltage converter connected to the electrical energy harvesting interface for generating a regulated voltage. The harvesting interface samples an open-circuit voltage value of the transduced signal, generates an optimized voltage value starting from the open-circuit voltage value, and generates an upper threshold voltage and a lower threshold voltage on the basis of the optimized voltage value. The harvesting interface controls the voltage converter in switching mode so that the harvesting signal has a value between the upper and lower threshold voltages in at least one operating condition.

摘要： A control apparatus charging a storage battery is provided. A control apparatus controls charging from a power generator to a storage battery. A switch is provided on a first charge channel via which the power generator charges the storage battery, and a DCDC converter is provided on a second charge channel via which the power generator charges the storage battery. The DCDC converter steps up a voltage generated by the power generator, and applies the stepped-up voltage to the storage battery via an electric wire. A controller controls the switch and the DCDC converter such that, when a charge current value detected by an electric current detector becomes smaller than a predetermined value under a condition where the storage battery is being charged via the first charge channel, charging to the storage battery is switched to charging via the second charge channel.
