Abstract: A mobile power system may include a bidirectional AC-DC converter configured to convert a grid AC signal to a power limited DC charging signal with a threshold level, a battery module configured to provide a DC power signal, and a controller coupled to the battery module and the bidirectional AC-DC converter and configured to selectively switch the bidirectional AC-DC converter between a first state and a second state. The first state may include, when a load power level is less than the threshold level, concurrently charging the battery module using the power limited DC charging signal and delivering the grid AC signal to a load. The second state may include, when the load power level is greater than the threshold level, concurrently converting the DC power signal with the bidirectional AC-DC converter into a battery AC signal for delivery to the load, and delivering the grid AC signal to the load.
