“…Therefore, the control of output power is indispensable. To reduce the cost, size, and complexity of the WPT system, the controller should be implemented on the primary side, without any measurement and communication devices on the secondary side [21][22][23]. The primary-side control can be realized through the inverter voltage control.…”

To achieve a free-positioning wireless power transfer (WPT) system, the output power must be regulated throughout the operation. This paper presents a novel output power control of a WPT system, based on the model predictive control (MPC). The output power is predicted by utilizing the system's mathematical model. The optimal duty cycle for a desired output power is obtained through the minimization of the objective function, which is simple and easy to implement, with no need for gain tuning. The proposed controller is implemented on the primary side, without any measurement or communication devices on the secondary side. This reduces the cost, size, and complexity of the WPT system. The load resistance and mutual inductance identification method is also introduced. It is based on the reflected impedance knowledge, where only the information of primary current is required. Experimental results of the output power step response show better performance compared with conventional Proportional-Integral (PI) control. The proposed controller is experimentally validated on a 200 W kettle. The output power can be kept constant at 200 W while the kettle is laterally moved. With the proposed controller, the kettle can be placed freely up to 7 cm from the align position, which is 63.64% of the primary coil's outer radius.

“…7 Also, they can be used as a constant current source for many applications such as battery charging 8 and LED driving, 9 by incorporating control methods or inherent properties of the PRTs. [10][11][12] Because the control methods require extra devices, such as sensors and feedback loop, cost and complexity of the converter can be decreased leveraging inherent properties of the PRTs. Making use of the immittance property in the 2-port networks, can be conceived as an effective inherent properties-based method.…”

Passive resonant tanks (PRTs) with immittance property are suitable candidates to achieve constant output current in load resonant converters (LRCs). In this paper, fifth-order Π-type LC networks are investigated to accede this target. At the first step, fifth-order Π-type passive LC networks that can be applied as a PRT are specified based on source and sink natures. Also, their structural advantages are described in detail to give a suitable perspective for the topology selection. At the second step, immittance property is verified for the proposed topologies and immittance PRTs (IPRTs), with their immittance operation conditions, are derived. To confirm the effectiveness, a 150-W LRC is implemented leveraging new Π-type IPRTs. A deep investigation is devoted to analyze the current/voltage stress in the components of the designed LRC. Moreover, kVA/kW ratio is considered as a key parameter for the reactive component size minimization. The proposed constant current LRC presents high load regulation capability in addition to the minimum reactive power and zero-voltage switching (ZVS) on the inverter MOSFETs under the various loads. A significant robustness against load variations, less sensitivity versus parameters variation, and relatively higher efficiency are the main superiorities of the fifth-order IPRTs to the lower order counterparts.
