Electrical current system including voltage drop component |
摘要 |
An electronic open-circuit current measuring circuit is configured to measure a current delivered between a current source and a load during an open circuit condition. The electronic open-circuit current measuring circuit includes an electronic voltage drop component electrically connected between a first buffer output and an electrical voltage difference calculating circuit. The voltage drop component is configured to reduce a first voltage level of the first buffered output voltage below a second voltage level of the second buffered output voltage in response to an open circuit condition. |

1. An electronic open-circuit current measuring circuit configured to measure a current delivered between a current source and a load during an open circuit condition, the electronic open-circuit current measuring circuit comprising:
a first electronic buffer operation amplifier that receives a first input voltage and generates a first buffered output voltage; a second electronic buffer operation amplifier that receives a second input voltage different from the first input voltage, and generates a second buffered output voltage different from the first buffered output voltage; an electrical voltage difference calculating circuit in electrical communication with the first buffer operation amplifier and the second buffer operation, the voltage difference calculating circuit configured to determine a voltage differential based on the first buffered output voltage and the second buffered output voltage; and an electronic voltage drop component electrically connected between the first buffer output and the electrical voltage difference calculating circuit, the voltage drop component configured to reduce a first voltage level of the first buffered output voltage below a second voltage level of the second buffered output voltage in response to the open circuit condition. |
