Variable-Parameter T-Circuit-Based IPT System Charging Battery With Constant Current or Constant Voltage Output

IEEE Transactions on Power Electronics, 2020
Load-independent output characteristics of inductive power transfer (IPT) systems are increasingly popular in battery charging. This paper proposes a novel variable-parameter T-circuit (VT) for an IPT system charging a battery with constant current (CC) or constant voltage (CV) output.

A New Coil Structure and Its Optimization Design With Constant Output Voltage and Constant Output Current for Electric Vehicle Dynamic Wireless Charging

IEEE Transactions on Industrial Informatics, 2019
Dynamic wireless power transfer (DWPT) is a promising solution to address electric vehicle range anxiety and to reduce the capacity and the cost of the on-board batteries. In the traditional DWPT system, the mutual inductances among the transmitters make the design of compensation networks very complex.

Constant current and constant voltage output WPT system based on LCC compensation network

2020 IEEE International Conference on Mechatronics and Automation (ICMA), 2020
In this paper, the LCC compensation network is applied in the MCR-WPT system to achieve constant voltage and constant current characteristics which is required for battery charging. The configuration and parameters of the LCC network are obtained through the analysis of the working principle.

A Wireless Power Transfer System with Multiple Constant Current and Constant Voltage Outputs

2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019
This paper proposes a novel multi-load wireless power transfer (WPT) system with both constant current (CC) and constant voltage (CV) outputs. Repeater coils are used and every two repeater coils form a repeater unit. The bipolar coils are adopted in the proposed WPT system and the two coils in the same repeater unit are placed perpendicularly to ...

Current- and Constant-Dollar Input-Output Forecasts for the U. S. Economy

Journal of the American Statistical Association, 1976
Abstract Utilizing recently deflated and reconciled U.S. Department of Commerce input-output data from 1947, 1958, 1961, 1963, and 1966, this paper presents an empirical test of the accuracy of input-output forecasts in current dollars and in constant dollars.

2.5A-Constant-Output-Current, Constant-T_off , 1.5 MHz, 89%-Efficiency Switching Converter

IEEE Transactions on Circuits and Systems II: Express Briefs
In this paper, a Constant-Output-Current, constant-Toff, buck-mode switching converter is presented. The device uses a Peak Current Mode Control (PCMC) with an integrated High-Side (HS) current sensing and, with typical voltage regulator solutions, delivers a constant output current. The proposed concept is validated by an IC prototype in a 0.35 μm BCD

The infeasibility of constant output power in a constant-current-fed class-E power inverter

IEEE Transactions on Industrial Electronics, 1991
It is shown that it is impossible to configure a constant-current-fed class E inverter to provide constant output power independent of load, except for a trivial circuit in which the output power is zero. The basic equations and the requirements for load-independent power are discussed. >

Primary-Side Peak Current Measurement Strategy for High-Precision Constant Output Current Control

IEEE Transactions on Power Electronics, 2015
The objective of this paper is to propose the primary-side peak current measurement strategy (PCMS) for the high-precision constant output current converter. The primary-side regulator (PSR) is widely used for low-cost and low-power light-emitted diode (LED) lighting application with universal input voltage range.

A Constant Current Output System for ICPT without Complex Control

2018 International Symposium on Computer, Consumer and Control (IS3C), 2018
In view of the poor output stability and complex constant current control of the partial induction coupled wireless power transmission system, the present study proposes a push-pull inductively coupled soft-switching power transmission converter for series-parallel leakage inductance compensation, so that wireless power system can achieve constant ...
