REDUNDANT RESIDENTIAL POWER SOURCES

摘要

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for controlling a battery power source. In one aspect, a system includes a first MOSFET having a first gate, a first source, and a first drain. A second MOSFET having a second gate, a second source, and a second drain. The first source is connected to the second source, and the second drain is coupled to a ground. A control circuit connected to the first gate and the second gate and that provides control signals to the first gate and the second gate that cause the first and second MOSFETS to operate in saturation regions during a first operational state to cause the first power source to discharge and the first MOSFET operates in a linear region during a second operational state to limit a charging current that charges the first power source.

1. A system, comprising:
a first MOSFET having a first gate, a first source, and a first drain; a second MOSFET having a second gate, a second source, and a second drain, wherein the first source is connected to the second source, and the second drain is coupled to a ground; a first power source having a first power terminal and a second power terminal, wherein the first power terminal is connected to the first drain and second power terminal is connected to a DC bus; a second power source having a third power terminal and a fourth power terminal, wherein the third power terminal is connected to the ground and the fourth power terminal is connected to the DC bus; and a control circuit connected to the first gate and the second gate and that provides control signals to the first gate and the second gate that cause:
the first and second MOSFETS to operate in saturation regions during a first operational state to cause the first power source to discharge; andthe first MOSFET operates in a linear region during a second operational state to limit a charging current that charges the first power source.
