In the next 5 to 10 years, digital Artificial Intelligence with Machine Circuit Learning Algorithms (MCLA) will become the mainstream in complex automated robots. Its power concerns, ethical perspectives, including the issues of digital sensing, actuation, mobility, efficient processcomputation, and wireless communication will require advanced neuromorphic process variable controls. Existing home automated robots lack memristic associative memory. This work presents Cyber-Physical Home Automation System (CPHAS) using Memristive Reconfigurable Algorithmic State Machine (MRASM) chart. A process control architecture that supports Concurrent Wireless Data Streams and Power-Transfer (CWDSPT) is developed. Unlike legacy systems with powersplitting (PS) and time-switching (TS) controls, the MRASM-ROBOT explores granular wireless signal controls through unmodulated high-power continuous wave (CW). This transmits infinite process variables using Orthogonal Space-Time Block Code (OSTBC) for interference reduction. The CWDSPT transmitter and receiver circuit design for signal processing are implemented with complexity noise-error reduction during telemetry data decoding. Received signals are error-buffered while gathering control variables' status.Transceiver Memristive neuromorphic circuits are introduced for computational acceleration in the design. Hardware circuit design is tested for system reliability considering the derived schematic models for all process variables. Under small range space diversity, the system demonstrated significant memory stabilization at the synchronous iteration of the synaptic circuitry.

“…In terms of coil design, expanding the area of the transmitter coil can effectively improve the misalignment tolerance of the receiver coil and reduce the mutual inductance variation of the transmitter and receiver coils. 14,15 However, this method will lead to an increase in the volume of the coil of the WPT system, as well as an increase in magnetic flux leakage which will worsen the transfer efficiency of the system. Under the condition of fixed coil volume, coil structures such as double-D (DD) coil, 16 DD quadrature (DDQ) coil, 17,18 and DD two-quadrature (DD2Q) coils have better misalignment tolerance compared with conventional unipolar coils.…”

SummaryThis article proposes an adaptive feedback regulation method for wireless power transfer (WPT) systems, which can be applied to solve the problem of the drop in input voltage from the emergency power supply such as a battery‐based source. The whole WPT system transfers power mainly through the mutual inductance between the transmitter and receiver coils. The compensation coils are accessed to form the power feedback side, which can achieve constant voltage output by adjusting the duty cycle of the DC/DC converter. Furthermore, the finite element simulation result analyzes the constant voltage output characteristics of the proposed topology under different load conditions. Finally, an 85 kHz prototype based on the proposed method is built and tested to verify the performance and effectiveness of the design. The proposed method achieves a constant 48 V output when the load varies from 60 to 120 Ω and the horizontal offset distance varies from 20 to 80 mm.

The output characteristics of WPT systems with repeaters have been widely studied and optimized, [10][11][12][13] and further research has expanded the repeater from a single direction to a two-dimensional plane.…”

The new multi-stage wireless power transfer (WPT) systems based on seriesparallel-series (SPS) and inductor-capacitor-capacitor (LCC) compensations (SPS-WPT and LCC-WPT) are characterized by constant output current and high transmission efficiency. To obtain applicable conditions and performance differences of these two systems, their output characteristics have been studied by theoretical derivation and experimental verification. First, the equivalent models of double-stage SPS-WPT and LCC-WPT systems have been built. Second, comparative analysis of two key compensation components that affect the output performance of the two systems has been completed. Third, the influence of each stage load and coupling conditions on the output performance of the two systems has been further analyzed and compared. Finally, output performance of the two systems has been tested and compared on a newly built experimental platform. Experimental results show that the output power and transmission efficiency of the SPS-WPT system reach 180 W and 80.39% with offset of 20 mm, which is more suitable for high power applications with low and fixed coupling condition. In addition, the output power and transmission efficiency of the LCC-WPT system reach 127 W and 85.92% with offset of 10 mm, which is more suitable for high efficiency applications at medium and variable coupling conditions.
