Abstract
An electronic uninterruptible power supply unit includes one or more battery connections. A bi-directional converter is in electrical communication with the one or more battery connections and arranged to (a) provide power at a first controlled voltage from the one or more battery connections as a boost converter when power is determined to not be available from a power source; and (b) provide charge to the one or more battery connections by providing power at a second controlled voltage that is different from the first controlled voltage when power is determined to be available from the power source. First and second MOSFET switches are connected in series with the one or more battery connections and arranged as a bi-directional switch that controls charging current for the one or more battery connections.
