Optimization control strategy of wide ZVS range and automatic Euler angle for bi-directional wireless power transfer system by TPS

Year: 2025

Type: article

Abstract: In this study, a control strategy for broad ZVS operating range and BDWPT system efficiency optimization was created. The matching requirements for using TPS (three phase shift) in a BDWPT system with a double-sided LCC compensated network are investigated. To manage power flow and match loads, an optimum TPS control mechanism is recommended. The frequency and time domain models of the double-sided LCC compensated network are suggested to further explain the behavior of the BDWPT system. By analyzing the resonant currents, a technique for operating the automated Euler angle function under TPS and redistribution of the fundamental phase shift angle is proposed. These evaluations reveal that the system can operate within a broad ZVS operating range under the majority of load scenarios with the suggested TPS control strategy. A 3.3kW BDWPT system prototype is created to verify the theoretical analyses. The observed waveforms and the suggested model correspond rather well. The system’s measured peak efficiency is 90.35%. All power switches achieve ZVS with wide coupling coefficients for various output scenarios over the whole power and transmission range.
