Abstract
A portable power station (PPS) unit includes a controller that receives AC current information of AC input current at an AC input port and produces a control signal that is used to control the PPS unit to operate as a voltage source or a current source, and to control an AC output current at substantially the same magnitude, frequency, and phase as the AC input current. A PPS apparatus includes two or more PPS units connected together such that the AC output power of one PPS unit is connected to the AC input port of a next PPS unit; wherein a first PPS unit is a voltage source and each of the second or more PPS units is a current source, and a total AC output power of the PPS apparatus is substantially a sum of the AC output power produced by the two or more PPS units.
