摘要： A dual input AC/DC power converter (10) having dual inputs (12,14) adapted to receive both an AC and DC input and provide a selectable DC voltage output (16) and a second DC output (18). The dual input AC/DC power converter (10) comprises a power converter circuit (20) having an AC-to-DC converter (22), a DC-to-DC booster converter (24), a feedback circuit (26), a filter circuit (25) and a DC-to-DC buck converter (28). Advantageously, the power converter (10) resolves many of the system management problems associated with carrying all of the different interface components necessary to power a wide variety of mobile products from either an AC or DC power supply. In addition, the feedback circuit (26) comprises single feedback loop having stacked photocouplers, one (PH1) controlling the AC-to-DC converter (22) and the other (PH3) controlling the DC-to-DC booster converter (24), to select the overall DC output voltage.

摘要： A dual input battery assisted power converter (10) which provides a continuous, regulated DC voltage output to a user-connected mobile device, such as, a lap top computer or a cell phone, for example. The power converter (10) comprises a power supply circuit (12) and a separate, detachable power storage circuit comprising a battery pack (14) having a re-chargeable battery (36). The power supply (12) is adapted to deliver a pair of regulated DC output voltages, of opposite voltage potentials, to a pair of respective output terminals. Preferably these output voltages are derived from two external input voltages: an AC input voltage and a DC input voltage. Advantageously, if both of the external input voltages are temporarily removed, the battery pack (14) will advantageously serve as a substitute DC input power source, thereby allowing the power supply (12) to deliver the same regulated DC output voltage to the user-connected mobile device without interruption. Moreover, once either of the external input voltages are again re-established, the battery pack (14) automatically taps the output terminal of the power supply (12) at a node to recharge the battery pack (14).
