Abstract
An electrical circuit providing for equal power consumption by the included oad elements when selectively energized by independent power sources of differing voltages, through control of the path of current flow through the load elements by rectifiers, the rectifiers being disposed to permit current flow in a direction through the load elements in series when a high voltage source energizes the circuit through one pair of terminals and, without alteration of the circuit, in parallel through the load elements when a low voltage source energizes the circuit through another pair of terminals.
Claims9
An electrical circuit configuration for producing equal power consumption by equal loads when energized selectively from multiple power sources having voltages of differing magnitudes comprising:
- a. first and second equal load elements each having a first terminal thereof connected to a first conductive lead and a second terminal thereof connected to a second conductive lead;
- b. a rectifier serially connected between said load elements in said first conductive lead;
- c. said first and second conductive leads adapted for connection selectively to a first and second power source having voltage of differing magnitudes with the ratio of voltage magnitude of said second power source to the voltage magnitude of said first power source equal to the total number of said load elements;
- and
- d. said rectifier connected for corresponding current flow so that when said electrical circuit configuration is energized selectively by unidirectional current from said first power source said rectifier presents a low resistance to current flow and said load elements are connected in parallel and when said circuit configuration is energized selectively by unidirectional current from said second power source said rectifier presents a high resistance to current flow and said load elements are serially connected, said load elements consuming equal power for parallel and serial connection.
