The 300W Wi-fi Energy Switch system is designed for powering gadgets reminiscent of drones and EVs, reaching over 90% effectivity with a compact design.
Wi-fi Energy Switch (WPT) expertise is gaining prominence resulting from its skill to supply energy with out bodily connections, providing numerous benefits throughout numerous purposes. By eliminating the necessity for cables, WPT enhances comfort, security, and sturdiness, making it significantly useful for gadgets requiring frequent charging or working in hazardous situations. It additionally permits for higher design flexibility and helps superior cellular and difficult-to-access purposes. The 300W Wi-fi Energy Switch reference design by Microchip features a Energy Transmitter and a Energy Receiver.Â
The transmitter’s design makes use of the WP300TX01 machine, whereas the receiver employs the WP300RX01 machine. This 300W system is completely suited to numerous purposes, together with energy instruments, vacuum robots, industrial slip rings, small electrical autos, and drones. The transmitter sometimes attracts energy from a 24V rail, and the receiver outputs a regulated voltage of 24V. The system achieves over 90% effectivity at 300W energy and operates with a 5-10 mm Z-distance.
The 300W electromagnetic inductive wi-fi electrical energy transmission purposes embrace numerous makes use of, reminiscent of e-bikes, drones, energy instruments, robotic vacuum cleaners, and lawnmowers. Moreover, it will possibly energy 5G routers, underwater lighting, and numerous in-vehicle purposes. This expertise can also be adaptable for client electronics, together with laptops.
The system options embrace a nominal DC enter voltage of 24V, with an working vary of 11V to 37V. It affords as much as 90% effectivity at an influence output of 300W. Security options embrace international object detection, NFC/RFID card detection, enter overvoltage and Undervoltage safety, and overcurrent and overtemperature safety. The utmost output energy of the receiver can attain as much as 300W, with a most present of 8.5A. The nominal output voltage of the receiver is about at 24V, however it may be adjusted from 12V as much as 36V. Optimum effectivity is achieved when the DC enter and receiver output voltage are intently aligned.
When activated, the system transmits receiver info and suggestions to the transmitter, guaranteeing environment friendly communication between parts. Moreover, the system consists of overpowering safety to forestall injury from extreme energy supply. It additionally supplies a regulated DC output voltage, sustaining steady and secure operation throughout numerous purposes.
The 300W Energy Transmitter is designed to interface with a removable OLED board, using the SPI communication protocol for information alternate between the transmitter and the board. The following part features a desk detailing the OLED display and displayed information. This info is meant primarily for board debugging functions. For OLED board might not be mandatory for the ultimate resolution.
