An IPT System with Constant Current and Constant Voltage Output Features for EV Charging
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018Inductive power transfer (IPT) system for electric vehicle battery charging has many advantages over the traditional plug-in system. EV battery can be regarded as a wide range load according to the charging profile. The charging process requires constant current (CC) stage and constant voltage (CV) stage.

2020 IEEE International Conference on Power and Energy (PECon), 2020
This paper presents a novel design theory for radio frequency (RF) inverters. We project the zero-voltage-switching (ZVS) and zero-voltage-derivative-switching (ZVDS) load impedances on the Smith chart, and find out that their loci exhibit geodesic arcs.

A Load-Independent Wireless Power Transfer System With Multiple Constant Voltage Outputs
IEEE Transactions on Power Electronics, 2020A novel wireless power transfer (WPT) system is proposed to power the gate drivers in a multilevel converter to achieve a high insulation level. There are two requirements for the proposed WPT system. First, the WPT system should contain multiple outputs, each corresponding to one gate driver.

A Closed-loop Ultrasonic Wireless Power Transfer System with Constant Output Voltage
2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019Ultrasonic wireless power transfer (UWPT) is a reasonable method to power loads in enclosed metal container. For the existing open-loop UWPT system, the output voltage varies with different loads. In this paper, a closed-loop UWPT system with constant output voltage for different load resistances is proposed. Two pairs of piezoelectric transducers with

A novel resonant network for a WPT system with constant output voltage
2017 IEEE Conference on Energy Internet and Energy System Integration (EI2), 2017The primary side series-secondary side series (SS) compensation network of a wireless power transfer system has a simple structure. But its output voltage changes with different load resistances. This limits its applications in certain circumstances need a stable output voltage.

The X-ray Output of a Constant Potential High-Voltage Apparatus
The British Journal of Radiology, 1934Previous investigations of high voltage X rays have been extended to a detailed consideration of the output of an X-ray tube up to 370 K.V. A number of typical output curves are given. The theories of the intensity distribution in the continuous X-ray spectrum leading to the formula I = KV2 for the energy output of a tube are briefly discussed.
