摘要： Control circuitry uses modified average current mode control to regulate average current through an inductor of a power converter. Control circuitry uses modified average current mode control to regulate average current through an inductor of an active power filter. This average current mode control negates modulation of the average inductor current. In this way, output ripple current of the power converter does not have a significant effect on the input current drawn by the power converter.

摘要： An active-power filter includes control circuitry to combine an integrated output-voltage feedback signal, an input-voltage sense signal and an output-load feedforward signal to generate a control signal. An output-load subsystem draws the output current from the active-power filter and the output-load feedforward signal indicates when current drawn by an output-load subsystem changes. In some embodiments, the output-load subsystem may draw output current from the power converter having an output current ripple at a nominal frequency, which may range, for example, between about 35 and 100 Hz. The control circuitry may include an integrator to integrate the output-voltage feedback signal. The integrator may have a control loop bandwidth significantly less than the nominal ripple frequency to loosely regulate the output voltage while the input current drawn by the active-power filter is tightly regulated.

摘要： A current source that uses a regulated constant current power source to supply current to drive a load, and the load current is controlled by shunt switches. If a plurality of loads utilize less than 50% duty factor, then one current source can drive N multiple dissimilar impedance loads, each at 100%/N duty factor. The current source includes a power converter coupled between the power source and the load(s) for providing pulsed current thereto. A current sensor is provided for sensing current flowing through the loads. A controller is coupled between the sensor and the power converter for regulating the amplitude of the output current supplied to the loads. A shunt switch is coupled across the loads, and a duty factor controller is coupled to the shunt switch for setting the duty factor of the shunt switch. A laser drive circuit, or driving light emitting diode arrays is also disclosed that include a plurality of the current sources. Alternatively, if the duty factor is sufficiently low, one current source may be used to drive a plurality of arrays.

摘要： A thermoelectric cooler controller, a thermal reference source employing the controller, a thermal reference source, and a thermal calibration system. The controller controls the temperature of a thermoelectric cooler. The controller includes a temperature sensor coupled to the thermoelectric cooler that provides a temperature feedback signal. An error amplifier compares a temperature command (TEMP CMD) with a feedback signal and generates a positive polarity output current command signal (VCMD). A current driver is coupled to the error amplifier for providing an output current equal to one-half the current command signal. An H-bridge circuit is coupled between the current driver and the thermoelectric cooler for switching the direction of current flow in the thermoelectric cooler, thus heating and cooling it. A comparator is coupled to the error amplifier and the H-bridge circuit, for controlling the current supplied by the H-bridge circuit to the thermoelectric cooler. The thermal reference source comprises the thermoelectric cooler and the above-described controller. The detector system includes a detector, and the thermal reference source and controller. The thermal calibration system comprises the detector, the thermoelectric cooler for providing heat output to the detector, and the thermal reference source and controller.

摘要： Active power filters and methods control and regulate the input current drawn from an electric power bus to a DC level. Load current fluctuations and ripple current reflected back to the electric power bus are significantly reduced or substantially eliminated. A switch mode power converter with a very low bandwidth output voltage regulation control loop uses input voltage feedforward, output load feedforward, and output voltage feedforward to provide a regulated DC input current significantly attenuating input ripple current drawn from the electric power bus.

摘要： A quasi-resonant diode drive current source provides high power pulsed current that drives light emitting diodes, and the like. The pulsed output current of the quasi-resonant diode drive current source is sensed, and is regulated by a control loop to a level required by the light emitting diodes. In a specific embodiment of the invention, a zero-current-switched full wave quasi-resonant buck converter is described that provides a high amplitude pulsed output current required to drive light emitting pump diodes used in a solid state diode pumped laser. The use of a quasi-resonant converter as a pulsed current source provides a much higher conversion efficiency than conventional laser current sources. This higher efficiency results in less input power drawn from a power source and cooler operation, resulting in a higher reliability current source.
