At present, in the practical application of magnetic resonance wireless transmission technology, because of the change of distance, relative position between transmitting coil and receiving coil and load, the output power and transmission efficiency of transmission system will be greatly affected. Therefore, in order to improve the output power and transmission efficiency. In this paper, a new frequency tracking control algorithm based on Cascaded Generalized Integrator PLL (CGI-PLL) structure is proposed. The new frequency tracking control algorithm is used in the series-series circuit of magnetic resonance. It is planned to use this algorithm when the transmitting coil is detuning to a certain extent and the receiving coil is resonant at the same time. The phase compensation and soft switch are realized by controlling the phase difference between the output voltage and the output current of the primary side inverter. The experimental results show that the phase between the output voltage and the output current of the primary measurement inverter can remain unchanged when the load and mutual inductance are changed. Therefore, the CGI-PLL detuning control algorithm can actively track the frequency of the system, improve the output power and transmission efficiency of the system, and provide conditions for the operation of ZVS soft switch. It is proved that the new control algorithm proposed in this paper is feasible and correct.

“…The methods mentioned above are five typical PLLs for distorted and unbalanced grids. There are also many modified or improved PLLs based on these five typical PLLs, for example, the DSOGI-PLL with frequency-tracking [15], Multiple-SOGI-FLL (MSOGIFLL) [16], [17] and so on. However, these five PLLs are fundamental and typical.…”

This paper studies the performances of five typical Phase-locked Loops (PLLs) for distorted and unbalanced grid, which are the Decoupled Double Synchronous Reference Frame PLL (DDSRF-PLL), Double Second-Order Generalized Integrator PLL (DSOGI-PLL), Double Second-Order Generalized Integrator Frequency-Lock Loop (DSOGI-FLL), Double Inverse Park Transformation PLL (DIPT-PLL) and Complex Coefficient Filter based PLL (CCF-PLL). Firstly, the principles of each method are meticulously analyzed and their unified small-signal models are proposed to reveal their interior relations and design control parameters. Then the performances are compared by simulations and experiments to investigate their dynamic and steady-state performances under the conditions of a grid voltage with a negative sequence component, a voltage drop and a frequency step. Finally, the merits and drawbacks of each PLL are given. The compared results provide a guide for the application of current control, low voltage ride through (LVRT), and unintentional islanding detection.

SummaryMultisegment wireless power transfer (MSWPT) technology provides a solution to the challenges of dust‐free environments and automation faced by automated material handling systems (AMHS) in current semiconductor wafer factories. However, variations in track current frequency and phase offset on the transmitting side of the MSWPT technology may lead to significant deficits in energy transmission capability. This paper introduces a method based on the fixed‐frequency second‐order generalized integrator phase‐locked loop (FFSOGI‐PLL) structure for frequency and phase synchronization among multiple transmitters in a MSWPT system. By synchronizing the track currents of multiple transmitters, this method significantly enhances the energy harvesting capacity of the H‐type pickup in the overhead hoist transport (OHT) system, ensuring stable voltage at the receiver (Rx) load. Both theoretical simulations and experiments confirm that the proposed method can effectively capture the phase difference of track current and achieve frequency locking and phase tracking. Building on this theoretical foundation, we constructed three transmitter (Tx) systems and a 1.5 kW Rx equipped with an H‐type pickup. This setup is capable of real‐time monitoring and phase‐synchronization control of track currents with varying phase offsets. The results convincingly demonstrate the strong performance and stability of the proposed method.
