SummaryIn this paper, irregular 32 pulse density modulation (PDM)‐controlled wireless power transfer (WPT) system is proposed for constant current (CC) and constant voltage (CV) outputs. The proposed WPT system has a load independent ZPA frequency characteristic with CC and CV outputs. Thus, soft switching conditions are achieved for both CC and CV outputs. An experimental prototype was prepared to validate the effectiveness of the proposed irregular 32 PDM‐controlled WPT system. WPT coil design parameters are presented and analyzed with lateral and rotational misalignment conditions in ANSYS. The experiments were determined as 3 A for CC output and 200 V for CV output. The maximum efficiency of the proposed system is measured (95.34%) at aligned coils with 100 mm air gap. In addition, the efficiency results are presented and evaluated by performing experimental studies under both lateral and rotational misalignment conditions.

“…The PDM control can provide soft switching condition of semi active rectifier (SAR). It can also be adopted to the HFI at the transmitting side [8]. However, in PDM control, when the load decreases, current ripples are increased and therefore the optimization of pulse distribution is required.…”

This paper proposes an improved pulse density modulation (PDM) control for a semi active rectifier (SAR) in wireless power transfer (WPT) with LC/S compensation. In order to improve the output regulation performance of the WPT converter, an improved pulse density modulation (PDM) is used, and its control signals are applied to the switches of the SAR. Based on the improved PDM control, the pulse sequence of the SAR is distributed more evenly compared to the traditional PDM. Thus, the output voltage ripple of the WPT converter is decreased and the output current ripple of the high frequency inverter (HFI) is decreased as well. The soft switching conditions can be achieved for both the SAR and HFI switches. In addition, since the control is applied only to the receiving side, there is no necessary for the communication devices. A simulation study is carried out to verify the performance of the improved PDM control and compared with the traditional PDM control. Based on the simulation results, the ripples of the output voltage as well as the output current ripples of the HFI are effectively reduced by using the improved PDM. Finally, the experimental results are presented to validate the effectiveness of the proposed control method.
