A Misalignment-Tolerant Fractional-Order Wireless Charging System With Constant Current or Voltage Output

IEEE transactions on power electronics, 2022
Wireless charging of automated guided vehicles (AGVs) has been widely used because of its high security and convenience. However, due to the inevitable misalignment between the coupling coils, the charging system cannot maintain the constant current (CC)

Design of Constant-Voltage and Constant-Current Output Modes of Double-Sided LCC Inductive Power Transfer System for Variable Coupling Conditions

IEEE transactions on power electronics
It is crucial for inductive power transfer (IPT) systems to achieve load-independent outputs. However, the complex charging environment brings a series of challenges to the parameter design of the IPT system. For example, in the case of wireless charging

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.
