Portable alternating current inverter having reduced imipedance losses

An alternating current (AC) power supply system, comprising:

• an AC source connector for coupling to and receiving AC power from an AC power source;
• a power supply module coupled to the AC source connector and configured to receive the AC power from the AC source connector and comprising an output to provide the AC power;
• a battery system comprising a plurality of rechargeable battery cells configured to output DC power;
• an inverter configured receive AC power from the power supply module and receive DC power from the battery system and to output AC power at a predefined level;
• a control module coupled to the power supply module and the battery system and configured to monitor the AC power received by the power supply module and if the AC power received by the power supply module and supplied to the inverter is insufficient to enable the inverter to output the predefined level of AC power the control module instructs the battery system to provide DC power to the inverter to supplement the AC power provided to the inverter;
• and
• an outlet configured to receive AC power from the inverter.
