The possible wireless power transfer (WPT) consists of stationary and dynamic wireless power transfer (DWPT) for warehouse robots power charging. The stationary wireless charging for warehouse robots has several disadvantages of long charging time, non-running, frequent charging, etc., whereas DWPT is a broad application prospect and is considered one of the best solutions above-stated problems. This paper proposes a maximum transfer efficiency and distance method in the DWPT for Warehouse Robots using a magnetic resonant (MR) inductive coupling subsection coil powered by a transmitter coil (Tx). The optimal efficiency is reached when three adjacent subsection coil (SC) are simultaneously powered on a single Tx. The two critical parameters in DWPT are Power Delivered to the Load (PDL) and Power Transfer Efficiency (PTE). The design results of an MR inductive coupling and a magnetic resonant inductive coupling subsection coil (MRSC) WPT optimized for a 20 kHz operating frequency at 8-cm, 11-cm, and 16-cm coupling distance show PTE (an MR inductive/MRSC) WPT of 85/87%, 65/70%, 45/65%, respectively, and the PDL of the MRSC WPT 3.2%, 11.1%, and 50% respectively higher than an MR inductive WPT. Results also show that the robot moves smoothly along the transmission track, and having the MRSC underneath is a less complicated system.
