Abstract: An electrical system can include an isolated bidirectional converter (having an input couplable to a grid connection and an output couplable to a battery) and an isolated converter (having an input coupled to the input of the isolated bidirectional converter and couplable to the grid connection, with an AC output coupled to a convenience outlet). The electrical system can further include a controller that controls operation of the converters to operate in one of a plurality of modes including a charging mode in which the isolated bidirectional converter operates in a forward direction to charge the battery and the non-isolated converter powers the convenience outlet from the grid connection, and a non-charging mode in which the isolated bidirectional converter operates in a reverse direction to power the non-isolated converter from the battery and the non-isolated converter powers the convenience outlet.

Abstract: A power conversion system can include at least one stacked half bridge converter that further includes a first half bridge further comprising two switching devices in a half bridge configuration and a first capacitor coupled thereacross and a second half bridge further comprising two switching devices in a half bridge configuration and a second capacitor coupled thereacross. The at least one stacked half bridge converter can be disposed between an input of the power conversion system and an output of the power conversion system. The power conversion system can further include a transformer coupled to the at least one stacked half bridge converter by a blocking capacitor and control circuitry that operates the switching devices of the at least one stacked half bridge converter as a switched capacitor converter using the blocking capacitor as a flying capacitor to equalize charge between the first and second capacitors.

Abstract: An AC-AC converter can include a stack of four switches. An input of the converter can be coupled across the stack of four switches, and an output of the converter can be taken from first terminal coupled to a connection point of first and second switches of the stack and a second terminal coupled to a connection point of third and fourth switches of the stack. The converter can further include a controller that operates the switches such that during a positive half cycle of an AC input voltage, the first and second switches are operated with an alternating 50% duty cycle and the third and fourth switches are constantly on, and during the negative half cycle of the AC input voltage, the third and fourth switches are operated with an alternating 50% duty cycle and the first and second switches are constantly on.
