Abstract
A device includes an input converter, an output converter, and a controller. The input converter is electrically coupled to an electrical meter and an energy production array. The output converter is electrically coupled to the energy production array and a load. The controller is communicatively coupled to the input converter, the output converter, the energy production array, and the load. The input converter and the output converter are positioned between the electrical meter and the load.
Claims6
A system, comprising:
- a first pulse-width modulation (PWM) converter coupled to a meter and a DC-link, the first PWM converter configured to convert an input AC waveform from a utility feed into a DC waveform;
- a second PWM converter coupled to the first PWM converter, the DC-link, and a load, the second PWM converter configured to convert the DC waveform from the first PWM converter into an output AC waveform for the load;
- and
- a control module configured to:
- monitor a voltage and a current of the input AC waveform from the utility feed;
- monitor a voltage and a current of the output AC waveform for the load;
- provide one or more first instructions to maintain a unity power factor from the utility feed;
- provide one or more second instructions to draw a sinusoidal current from the utility feed;
- provide one or more third instructions to regulate the voltage of the output AC waveform for the load;
- provide one or more fourth instructions to inject power flow into the utility feed at the unity power factor;
- and
- measure an amount of energy flowing into an out of the first PWM converter;
- wherein a neutral line from the utility feed is coupled to the first PWM converter, the DC-link, and the second PWM converter.
