    Abstract: A programmable AC/DC power converter receives a plurality of input voltages and outputs a single voltage from an input voltage system. A transformer receives the single voltage. One of the plurality of input voltages is provided at a center tap of a secondary winding of the transformer. A transformed voltage is output. A rectifier receives the transformed voltage and outputs a DC voltage. A buck regulator receives a DC voltage, creates a regulated voltage, and outputs the regulated voltage and a regulated current to a portable appliance. A error correction system receives a programming signal and regulated signals and verifies that the regulated signal to programming signal ratio is within an acceptable range.

    Abstract: A bi-directional boost circuit for power factor correction includes a power factor control circuit and a pair of diodes, a pair of inductors, and a pair of switches. A first diode, a second diode, a first inductor, a second inductor, a first switch, and a second switch convert the AC input voltage, rectify the AC input voltage, and output an intermediate DC voltage. The power factor control circuit receives the AC input voltage and receives the intermediate DC voltage. The power factor control circuit regulates the DC output voltage. Based on the AC input voltage and the intermediate DC output voltage, the power factor control circuit controls an inductor current waveform by driving the first switch and the second switch to create a substantially sinusoidal current as seen by the power source that is in phase with the AC input voltage.

    Abstract: A power supply system includes an adapter to receive power from a power source, and output a regulated output voltage (Vout). A tip receives Vout from the adapter, and output Vout to an electronic device. The tip includes active circuitry to adjust a programming voltage (Vprog). Vprog is fed back to the adapter to control a magnitude of Vout.

    Abstract: A power converter with a fan assembly cools down a temperature of the power converter. The power converter with a fan assembly includes a housing, a plate, and a second plate. The housing includes a fan assembly (which is integral to the housing) to draw in air. The plate is coupled to the housing to create an air channel between the plate and the housing and the second plated is coupled to the housing to create a second air channel between the second plate and the housing. The fan assembly draws in air through one of the air channel or the second air channel and moves air out through the other of the air channel and the second air channel to cool down the temperature of the power adapter.
