Abstract: A digital power conversion system is described with a control system, power system, DC bus system, and AC bus system housed in a case. The user-programmable control system outputs pulse-width modulated (PWM) signals and input/output (I/O) signals. The power system uses these PWM signals to drive integrated power transistors to achieve a variety of power conversion functions. The DC bus system includes positive and negative DC buses accessible via positive and negative DC terminals and is connected to the power system, while the AC bus system comprises AC buses accessible via AC terminals and is also connected to the power system. The system provides an efficient and integrated power electronics platform at its rated ranges by harnessing digital power conversion and other techniques.

Abstract: The present disclosure relates to a system and a method for regulating an output voltage to a requested target voltage. The system includes a System-on-a-Chip (SoC) device and a Power Management Integrated Circuit (PMIC) having a voltage regulator. The SoC device configured to receive a requested target voltage, generates an analog voltage signal that steps up or down over time until the analog voltage signal corresponds to the requested target voltage, and outputs the analog voltage signal. The voltage regulator is configured to reference the analog voltage signal from the SoC device and supply a corresponding regulated output voltage to the SoC device.

Abstract: A battery charger is provided that includes a switching power converter that regulates an output voltage on an output voltage rail. A transistor couples between the output voltage rail and a rechargeable battery for a system. An error amplifier controls the conductance of the transistor based upon a difference between a battery current conducted by the transistor to the battery and a battery current threshold. A pulse width modulator controls a duty cycle of the switching power converter responsive to a selected error signal from a group of error signals. Based upon which error signal is selected for the duty cycle control, the battery charger either increases or decreases the battery current threshold to assist in keeping the output voltage above a minimum system voltage for the system.

Abstract: An analog-to-digital converter ADC and a method to convert an analog input signal into a digital output signal comprising N bits on, n?{0, . . . , N?1} is presented. The ADC contains a controller, a digital-to-analog converter DAC, and a comparator. The comparator generates a binary signal by comparing the analog input signal with an analog output signal of the DAC. The controller receives the binary signal generated by the comparator and generates, based on the binary signal, a digital control signal comprising N bits cn, n?{0, . . . , N?1}. The DAC generates the analog output signal based on the digital control signal generated by the controller. The controller has a register which stores a previous sum value and an adder to determine a test sum value by adding.

Abstract: A method has steps for receiving at a call center implemented in a network, a first call from a caller using a first telephony-enabled device, connecting the received first call to an agent in the call center, creating and storing in a data repository at the call center a live call record associating an identity of the caller or a device of the caller with the agent to whom the first call is connected, receiving, while the first call is active, a second call from the same caller using a second telephony-enabled device, querying the data repository and discovering the live call record, routing the second call to the same agent to whom the first call is routed, and terminating the first call, but leaving the live call record in place.
