Abstract
A portable power unit is provided that can be embodied in backpack, waist-pack, or other portable form. The portable power unit can include a battery, a bidirectional power processor, and a power port. The bidirectional power processor allows for direct current (DC) power exchange between the battery and the bidirectional power processor and a user selectable alternating current (AC) or DC power exchange between the bidirectional power processor and a power port through which a power source and an external load can be connected for charging and discharging of the electrochemical battery, respectively.
Claims12
A portable power unit, comprising:
- an electrochemical battery and a bidirectional power processor, wherein there is a direct current (DC) power exchange between the electrochemical battery and the bidirectional power processor to provide an external load with alternating current (AC);
- wherein the power unit can be used for charging and the electrochemical battery;
- wherein the bidirectional power processor comprises a controller, a plurality of switching poles, each switching pole connected in parallel with the electrochemical battery and a first capacitor connected in parallel with the electrochemical battery;
- wherein the bidirectional power processor operates the external load at a fundamental frequency;
- and
- wherein the bidirectional power processor is further configured to reduce the voltage and the fundamental frequency or to reduce the voltage while leaving the fundamental frequency fixed upon detecting a large load.
