“…The interest to use PSK signals grows due to the attractive properties of these signals represented by noise stabilities. Moreover, PSK signals are characterized by the simpleness of implementation so it is used as stationary units for wireless communication, navigating, and systems evolution [24]. BPSK is the simplest scheme of the PSK.…”

Wireless communication techniques have become more popular due to their characteristics. These systems adopt the digital modification application, which provides more information for transmission and compatibility with digital data services as well as high information security and quality improvement. Digital wave signal-based communication techniques such as PSK, FSK, ASK, and QPSK considered among the most significant digital modulation techniques. These technologies are a crucial part of digital communication systems. Digital communication devices designed by FPAAs can provide multiple communication without arranging new devices and can support new within seconds. FPAA is extremely easy to reconfigure and program concerning FPGA or DSP-based applications. This article offers real-time implementation of ASK, FSK PSK, and QPSK modulator techniques with low power consumption based on the capability for dynamic reprogramming of the FPAA AN231E04 device Anadigm. FPAA techniques provide growing application and high pliability in the implementation of analog circuits. The measurements achieved from the proposed modulated circuits show that the form and properties of the theoretical outcomes agree perfectly with the practical outcomes. FPAA techniques provide growing application and high pliability in the implementation of analog circuits for minimizing the time of design and testing. Another feature is the minimum power exhaustion (165 mw) due to the switched capacitor method used by the FPAA Chip, which gives a high accuracy process.

“…When the WPT system is used for charging batteries, it is needed to control the output voltage or current [16]. There are four types of technology to realize the CC/CV output of WPT system [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]. Firstly, an additional DC/DC converter is used behind the secondary side rectifier to achieve CC/CV output [17][18][19][20][21].…”

“…The output power of the system can be achieved by controlling the duty cycle or phase angle of the active rectifier. Thirdly, frequency modulation (FM) control [26], phase shift (PS) control [27,28], and delta-sigma pulse density modulation (ΔΣPDM) [29] are applied to achieve CC/CV output without additional hardware devices [29]. However, these control schemes are complex and require real-time data communication between the transmitter and the receiver.…”

A novel magnetic coupling resonance wireless power transfer (MCR‐WPT) system, which has constant‐current (CC) and constant‐voltage (CV) output characteristics suiting for batteries charging, is proposed in this paper. The hybrid compensation topology is adopted; in detail, the LCL‐P circuit topology is used in the CC mode, while the LCL‐S topology is used in the CV mode. Since the switchable components are only located at the receiving side of WPT, the switching can be controlled by the receiving side based on the batteries’ state without data communication between transmitting side and receiving side. Furthermore, an adjustable frequency tuning method which is based on proportion integration (PI) closed‐loop controlled by the transmitting side is applied to maximize the current of the transmitting coil. This method also can solve the frequency splitting problem, improving the stability and power of the system while the distance of the two sides changes. The performance of the proposed WPT system is verified by simulation and experiments. The experiment results show that the load current variation is less than 3% in the CC mode and the load voltage changes less than 5% in the CV mode, as the load resister changes from 5 to 20 Ω.

“…A composite control method is designed in [18] based on the linear active disturbance rejection control and impedance matching technology, realizing constant voltage output and transmission efficiency improvement, whereas the additional Buck-Boost may cause energy loss. Li et al [19] proposed an FM phase-shift keying communication technique for closed-loop maximum efficiency point tracking control, but the usage of a controllable rectifier increased the control difficulty. The pulse-frequency modulation conceived in [20] could suppress the switching losses while maintaining full-range soft-switching, thus improving the system efficiency, whereas the resulting increase of harmonic component must be taken into account.…”

This article focuses on the self- and mutual inductance variation of a coupler with ferrite in an Inductive Power Transfer (IPT) system. The mechanism of the variation was analyzed using the magnetic field splitting method, revealing that varying the reluctance leads to inductance variability. Additionally, the inductance variation trends were explored by Finite Element Analysis (FEA), based on which the input angle and voltage gain of an LCC-S type IPT system were calculated when coupler misalignment occurred. Then, an input voltage adjustment and frequency tracking compound control method was designed to neutralize the effect of inductance variability, which was validated by simulation. Finally, a prototype LCC-S type IPT system was fabricated. Experimental results reveal a 35.28% variation in self-inductance over the misalignment range, and the compound control managed to stabilize the output voltage and maintain the soft switching of the inverter with system efficiency remaining above 86% up to 94.27%. The proposed mechanism of inductance variation and compound control are instructive for solving the coupler misalignment problem in IPT systems.
