Composite Core Inductive Voltage Divider Automatic Test Equipment Using Continuously Varying Inductive Coupling

K Sciences proposes to develop a prototype, inductive voltage divider (IVD) producing a continuously variable ratio transformer capable of high resolution voltage division tuning and calibration, wide input voltage and frequency ranges, and state-of-the-art 0.01 ppm resolution for all ratios. The prototype IVD will integrate an innovative core design providing enhanced performance through the 10 Hz to 20 kHz input AC frequency range. The prototype system will be a modern and completely automated test equipment capable of local and remote control through cross-platform computer software and hardware interface. K Sciences innovative approach eliminates switching and transformer taps, to dramatically simplify the IVD design and construction producing a more reliable, accurate, and versatile ratio voltage divider with minimal signal noise over a continuously tunable spectrum of known ratios. The prototype test equipment will meet the requirements of ISO/IEC 17025 for traceability to the National Institute of Standards and Technology (NIST).
