Calibration device for AC/DC systems
| DWPI Title: Circuit for calibrating direct current or alternating current power supplies, has first reference sensor with first reference input and first reference output, first device under test sensor with first device under test input and first device under test output, coupler |
| Abstract: The present disclosure relates to calibration devices for alternating current (AC) and direct current (DC) systems. The calibration device includes a circuit with a first reference (ref1) sensor that has a ref1 input and a ref1 output. The circuit has a first device under test (DUT1) sensor with a DUT1 input and a DUT1 output. The circuit has a coupler, where the ref1 output and the DUT1 output are connected to a first input and a second input of the coupler respectively and the coupler has a coupler output. A ref1 heating element is adjacent to and electrically isolated from the ref1 sensor and a DUT1 heating element is adjacent to and electrically isolated from the DUT1 sensor. A ref1 power source is connected to the ref1 heating element, and a DUT1 power source is connected to the DUT1 heating element. |
| Use: Circuit for calibrating direct current or alternating current power supplies. |
| Advantage: The power calibration is used in a variety of applications to realize stable electronic operation of modern day devices. The device under test (DUT) power source is connected to the DUT 1 heating element, and a DUT1 power source connected to a device-under-test power source, and thus enables to calibrate the DC or AC power supplies in a simple and cost effective manner, and also reduces the size and weight of the calibration device. |
| Novelty: Circuit comprises a first reference (ref 1) sensor with a ref 1 input (102) and a ref 1 output (142), a first device under test (DUT 1) sensor with a DUT 1 input and a DUT 1 output, a coupler, where the ref 1 output and the DUT 1 output are connected to a first input and a second input of the coupler respectively and the coupler has a coupler output, a ref 1 heating element adjacent to and electrically isolated from the ref 1 sensor, a DUT 1 heating element (129) adjacent to and electrically isolated from the DUT 1 sensor (126), a ref 1 power source (110) connected to the ref 1 heating element, and a DUT 1 power source (130) connected to the DUT 1 heating element. |
