    摘要: A charge pump power converter efficiently provides electrical power by dynamically controlling a switch matrix of the charge pump. Instead of open-loop oscillator-based control, a dynamic controller provides power upon demand by sensing the output voltage and changing the operating frequency of the charge pump in response. Moreover, this closed-loop dynamic control intrinsically voltage regulates the output voltage of the charge pump power converter without the inefficient addition of a step-down voltage regulator, downstream of the power converter. In addition, this closed-loop dynamic control allows for maintaining a desired output voltage even with variations in the input voltage. Also, the dynamic control accommodates the advantages of using ultra-capacitors in the charge pump. The power converter is capable of operating with a sub-one volt input voltage incorporating low-threshold, low on-resistance power MOSFET switches in the switch matrix of the charge pump. A progressive start-up circuit further allows the power converter to start from a discharged state even with a sub-one volt input voltage.

Instead of open-loop oscillator-based control, a dynamic controller provides power upon demand by sensing the output voltage and changing the operating frequency of the charge pump in response. Moreover, this closed-loop dynamic control intrinsically voltage regulates the output voltage of the charge pump power converter without the inefficient addition of a step-down voltage regulator, downstream of the power converter. Additional efficiencies are achieved through maintaining the voltage ripple across the fly capacitor and/or the load capacitor. Also, a three-state control scheme is used to charge the fly capacitor, wait for the output voltage to drop to a predetermined level, and discharge the fly capacitor. Furthermore, a multiple-output charge pump power converter provides multiple voltage levels for devices such as portable communication electronic devices.

    摘要: A charge pump power converter efficiently provides electrical power by dynamically controlling a switch matrix of the charge pump that includes a flying ultra-capacitor CUF. Instead of open-loop oscillator-based control, a dynamic controller provides power upon demand by sensing the output voltage and changing the operating frequency of the charge pump in response. Moreover, this closed-loop dynamic control intrinsically voltage regulates the output voltage of the charge pump power converter without the inefficient addition of a step-down voltage regulator, downstream of the power converter. In addition, this closed-loop dynamic control allows for maintaining a desired output voltage even with variations in the input voltage. Further efficiency is achieved by controlling the charging and discharging of the flying ultra-capacitor CUF, both in rate of current change and in voltage ripple.

    摘要: A power converter for coupling an energy source to a load device comprising a selectively coupled output stage to deliver energy from an energy source to a load device, a controller coupled to the output stage, an output stage, a capacitive element coupled to the output terminals, a rectifying element, and a switch responsive to a control signal from the controller. The rectifying element and switch are coupled to the inductive and capacitive elements. The controller is responsive to input signals for generating the control signal to open the switch in a first state and close the switch in a second state. The input signals to the controller produce one or more output voltages across the output terminals, an input voltage across the input terminals, a selectable reference voltage and a feedback signal measured with respect to the inductive element.

    摘要: Single and multiple cell batteries are provided with built-in controllers that monitor the cell or cells and provide a safety disconnect when certain monitored conditions are detected by the controller. Preferred single and multiple cell batteries have their cell or cells within a container having a positive terminal and a negative terminal. The built-in controller monitors the cell or cells for each of the following conditions: over temperature, short-circuit, overcharge, and over-discharge and the controller provides a safety disconnect when one of the monitored conditions exist. A multiple cell battery includes a built-in controller that monitors the temperature of the cells and provides a safety disconnect that electronically disconnects all of the cells when at least one of the cells exceeds a predetermined temperature, or a controller that monitors the state of charge of each of the cells and individually controls the charge cycle of each of the cells, or a controller that monitors the temperature of the cells and to provides a safety disconnect when at least one of the cells exceeds a predetermined temperature.

    摘要: A parasitic power supply provides for drawing power for an auxiliary device from a set of sequentially driven loads. A typical source of power is a traffic signal wherein the power may be sequentially applied to red, green and yellow lamps. The design provides isolation between loads so no two loads will be powered through any single-point failure of the power supply. The device may further contain control elements such as time delays to make the system compatible with requirements of safety devices used in traffic control systems to sense burned-out bulbs, and to sense conflicts between lighting patterns that are supposed to be mutually exclusive. The device may be configured as a separate component, or it may be integrated into a traffic signal head or into any selected device intended for connecting to a traffic signal head. The invention is particularly suitable for standard systems operating nominally at 115 VAC, though other AC voltages, and direct-current supplies, can also be used.
