IEEE Transactions on Power Electronics, 2015
The inductive power transfer (IPT) technique in battery charging applications has many advantages compared to conventional plug-in systems. Due to the dependencies on transformer characteristics, loading profile, and operating frequency of an IPT system, it is not a trivial design task to provide the battery the required constant charging current (CC ...

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 ...

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.
