Abstract
In order to improve volumetric power density or gravimetric power density and reduce passive component losses of the power-receiver in inductive power transfer (IPT) system, a LCCN (inductor-capacitor-capacitor-none) compensated IPT system is proposed in this paper. The secondary compensation topology is eliminated to construct a compact and light-weight power-receiver. And a design method for the open-loop IPT system to achieve not only load-independent constant current (CC) output or constant voltage (CV) output transfer characteristics but also load-independent zero phase angle (ZPA) operating conditions is investigated. With the proposed method, the VA ratings of inverter is reduced and DC-DC converter for CV output is discarded to reduce system cost and power losses. At last, a compact LCCN compensated IPT system for automated guided vehicle (AGV) was designed and system parameters according to configuration requirements was calculated. A 1.0 kW MATLAB simulation platform and experimental prototype have been implemented to demonstrate the feasibility and validity of the theoretical analysis. The efficiency of the system can reach 92.046% at CC mode and 93.675% at constant voltage CV mode.
