摘要： A control device, an electronic apparatus, a contactless power transmission system, and the like that can suppress deterioration in battery characteristics caused by recharging and realize power saving or the like. A control device on a power receiving side in a contactless power transmission system including a power transmitting device and a power receiving device includes: a charging unit that charges a battery based on power received by a power receiving unit that receives power from the power transmitting device; a discharging unit that performs an operation of discharging the battery and supplies the power from the battery to a power supply target; and a control unit that controls the discharging unit. The control unit starts the discharging operation of the discharging unit after an output voltage (VCC) of the power receiving unit has decreased and a start-up period (TST) of the discharging operation has elapsed.

摘要： Systems and techniques are provided for a self-powered energy harvesting circuit. A power generating mechanism may include power generating elements that generate alternating current signals. Rectifier circuits may each include a rectifier that generates a direct current signal from an alternating current signal. Group circuits may connect a group of the rectifier circuits in an electrical circuit to combine the direct current signals from the rectifier circuits in the group into a single direct current signal. Energy storage devices may be connected to the group circuits. The outputs of energy storage devices may be combined into a single output. The single output split into a primary output and a secondary output. A switch may be connected to the primary output. A controller may be connected to the secondary output and to the switch. The controller may control the switch. A voltage regulator may be connected to an output of the switch.

摘要： A switching power supply device includes a first switch, a second switch, a current sensing portion configured to sense current flowing in the second switch, and a controller configured to control the first and second switches. The controller controls the first switch and the second switch in accordance with current sensed by the current sensing portion if a ratio of the output voltage to the input voltage is a predetermined value or lower, and controls the first switch and the second switch independently of the current sensed by the current sensing portion if the ratio of the output voltage to the input voltage is higher than the predetermined value.

摘要： In a PoDL system, a PHY has its I/O terminals coupled to a wire pair via a galvanic isolation transformer and a CMC. Thus, DC power and common mode noise are blocked from the PHY inputs. One end of the secondary winding of the transformer is directly coupled to one winding of the CMC. A DC power supply has its positive voltage terminal directly coupled to the other end of the secondary winding and has its other output terminal (e.g., ground) directly coupled to the other winding of the CMC. An AC-coupling capacitor is coupled between the two outputs of the power supply. Differential signals are applied across the secondary winding to couple the differential signals to the PHY, while the secondary winding conducts the DC voltage to one of the wires (via the CMC), and the ground is coupled to the other one of the wires (via the CMC).

摘要： A distributed power network includes a power bus infrastructure distributed over a region with node points provided to interface with controllable power nodes. Each power node can be connected to an external power device such as a DC power source, a DC power load, or a rechargeable DC battery. The power nodes form a communication network and cooperate with each other to receive input power from DC power sources and or rechargeable DC batteries connected to the power bus infrastructure and distribute the power received therefrom to the power bus infrastructure for distribution to the DC power loads and to rechargeable DC batteries.

摘要： An equivalent-conductance-compensated globally-linear symmetric method for obtaining power flows in a DC power network, including: establishing an equivalent-conductance-compensated globally-linear function that relates all bus translation voltages to a bus injection power according to given bus load parameters and given bus source parameters of the DC power network; establishing an equivalent-conductance-compensated globally-linear symmetric matrix-equation model for power flows in the DC power network according to the equivalent-conductance-compensated globally-linear function and a given slack bus serial number; establishing an equivalent-conductance-compensated globally-linear symmetric matrix relation between non-slack bus injection powers and all the bus translation voltages by using M-P inversion of matrices according to the equivalent-conductance-compensated globally-linear symmetric matrix-equation model; and calculating each bus per-unit voltage and each branch-transferred power in the DC power network according to the equivalent-conductance-compensated globally-linear symmetric matrix relation.

摘要： A watchdog monitoring system having a watchdog integrated circuit and a microcontroller is provided. The microcontroller has a microprocessor, and a digital input/output device with an enable pin and a disable pin. A disable application in the microcontroller monitors the enable pin of the digital input-output device, and if the enable pin does not have a high logic state within a predetermined amount of time after a first time indicating that the microcontroller is malfunctioning, then the disable application generates a control message.
