A Three-bridge Topology for Constant Current and Constant Voltage Output in IPT System
2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018In this paper, a topology is proposed which used three-bridge switching compensation network for load-independent constant current (CC) and constant voltage (CV) output with fixed-frequency in Inductive Power Transfer (IPT) system. The leakage inductance model of Loosely Coupled Transformer (LCT) is used to analyze resonant conditions of CC and CV ...

Conference on Precision Electromagnetic Measurements. Conference Digest. CPEM 2000 (Cat. No.00CH37031), 2002
We developed a cryogenic constant current source with linear output by using a cryogenic current comparator. When changing the current supplied to a resistor, nonlinear change of its voltage drop corresponds to current dependence of its resistance. We used a Josephson potentiometer with high linearity to measure the voltage drop.
