Analysis of Compensation Topology with Constant-Voltage/Current Output for Multiple Loads Capacitive Power Transfer System
摘要
Abstract
As the main effective method of Wireless Power Transfer (WPT)
Capacitive Power Transfer (CPT) has received extensive attention recently. For a CPT system
compensation topology is significant in improving system transfer power and controlling output characteristics. While the current research on multiple CPT systems only focus on the specific circuit
lacking systematic study on constant-voltage (CV) or constant-current (CC) output. This paper studies a general compensation topology model of a multiload CPT system based on CV and CC output characteristics. First
the general circuit model of primary and secondary compensation topology based on a T-type or ∏-type circuit is constructed with the coupler's simplified induced current source (ICS) model. A universal design method of the multiload CPT system is given. Then
according to the proposed theory
a multiload CPT system based on double-sided LCLC compensation topology is analyzed
achieving CC output
maximum coupler transfer power and zero phase angle between input voltage and input current. Lastly
an experimental setup of double loads CPT system with 500W &500W is carried out. When load resistance changes from 50 ohms to 100 ohms
