Abstract
A mobile power system may include AC-DC converter configured to convert a grid AC signal to a power limited DC charging signal, a DC-AC converter coupled to the AC-DC converter, and a battery module configured to provide a DC power signal. The mobile power system may include a switching circuit coupled between the battery module, and the AC-DC converter and the DC-AC converter. The switching circuit may have a switch, and first and second diodes coupled in parallel to the switch. The mobile power system may include a controller coupled to the battery module, the switching circuit, and the DC-AC converter. The controller may be configured to selectively switch the switching circuit between a first state, a second state, and a third state.
