The 300W Wi-fi Energy Switch system is designed for powering units comparable to drones and EVs, reaching over 90% effectivity with a compact design.
Wi-fi Energy Switch (WPT) expertise is gaining prominence resulting from its capability to supply energy with out bodily connections, providing varied benefits throughout varied functions. By eliminating the necessity for cables, WPT enhances comfort, security, and sturdiness, making it notably helpful for units requiring frequent charging or working in hazardous circumstances. It additionally permits for higher design flexibility and helps superior cellular and difficult-to-access functions. The 300W Wi-fi Energy Switch reference design by Microchip features a Energy Transmitter and a Energy Receiver.
The transmitter’s design makes use of the WP300TX01 gadget, whereas the receiver employs the WP300RX01 gadget. This 300W system is completely suited to varied functions, together with energy instruments, vacuum robots, industrial slip rings, small electrical autos, and drones. The transmitter usually 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 functions embrace varied makes use of, comparable to e-bikes, drones, energy instruments, robotic vacuum cleaners, and lawnmowers. Moreover, it could actually energy 5G routers, underwater lighting, and varied in-vehicle functions. This expertise can also be adaptable for shopper 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 ready 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 data and suggestions to the transmitter, guaranteeing environment friendly communication between parts. Moreover, the system contains overpowering safety to forestall injury from extreme energy supply. It additionally offers a regulated DC output voltage, sustaining secure and secure operation throughout varied functions.
The 300W Energy Transmitter is designed to interface with a removable OLED board, using the SPI communication protocol for knowledge trade between the transmitter and the board. The next part features a desk detailing the OLED display screen and displayed knowledge. This data is meant primarily for board debugging functions. For OLED board will not be crucial for the ultimate resolution.
