Abstract
A circuit board includes a current balancing unit that receives a number of current values from ammeters. A minimum current value between the current values is determined by the current balancing unit. Resistance of one or more variable resistors of the current balancing unit is adjusted by the current balancing unit to make the current value from one or more the ammeters serially connected to the one or more the variable resistors to be substantially equal to the minimum current value.
Claims14
A circuit board, comprising:
- at least two circuits;
- at least two connectors, each of the at least two connectors configured to connect each of the at least two circuits to an external load;
- and
- a current balancing unit comprising at least two ammeters, a processing unit, and at least two variable resistors, each of the at least two circuits, each of the at least two ammeters, each of the at least two variable resistors, and each of the at least two connectors being connected in series, the processing unit connected to the at least two ammeters and the at least two variable resistors and configured to receive current values from the at least two ammeters, and to determine a minimum current value between the current values, and to adjust resistance of one or more of the at least two variable resistors to make the current value from one or more of the at least two ammeters serially connected to the one or more of the at least two variable resistors to be substantially equal to the minimum current value.
A circuit board, comprising:
- three circuits;
- three connectors, each of the three connectors configured to connect each of the three circuits to an external load;
- and
- a current balancing unit comprising three ammeters, a processing unit, and three variable resistors, each of the three circuits, each of the three ammeters, each of the three variable resistors, and each of the three connectors being connected in series, the processing unit connected to the three ammeters and the three variable resistors and configured to receive current values from the three ammeters, and to determine a minimum current value between the current values and to adjust resistance of one or more of the three variable resistors to make the current value from one or more of the three ammeters serially connected to the one or more of the three variable resistors to be substantially equal to the minimum current value.
