Ki Wireless Power Transceiver System (Tx)

This innovative Ki wireless power transceiver system (Tx) combines wireless power transfer and communication. Ki delivers up to 2kW of power with high-efficiency transfer, low-loss switching, minimal standby current, and dynamically adjusting power (0–2kW) for maximum energy efficiency. By eliminating appliance cables, Ki optimizes kitchen and home spaces, redefining convenience, safety, and performance for modern appliances.

Powered by Renesas' industry-leading NFC and MCU technology, this system features a capacitive touch display graphical user interface (GUI) and Bluetooth communication for monitoring and remote control. It enhances connectivity and user-friendly control by seamlessly integrating with appliances like extractor hoods. Designed for complete compatibility, the Ki wireless power transceiver system (Tx) interfaces directly with the Ki wireless power receiver system (Rx) for a fully integrated wireless power design.

System Benefits:

• Cordless operation eliminates appliance cables, maximizing countertop and workspace functionality, and supports a wide range of devices, from blenders and toasters to inductive cooking equipment like pots and pans.
• Dynamic power and appliance-side control provide seamless adjustment from 0kW to 2kW directly from the appliance side (Rx), enabling efficient and precise power management for enhanced user-friendly control and smarter operation of connected appliances.
• Industry-leading sinusoidal NFC technology reduces EMI, improves power efficiency, and enhances system reliability and longevity. Direct antenna connections lower signal loss, while smaller antennas enable compact designs and lower material costs.
• Flexible and scalable design can be easily integrated into a cooking hub or surface and supports a 1x to 4x scalable design, offering flexibility to accommodate a wide range of design requirements and applications.
• Low-loss switching and minimal standby current optimize performance and reduce power consumption.
• Optional Bluetooth^® Low Energy (LE) communication supports smartphone control and remote interfaces, allowing interaction with other appliances, such as an extractor hood, without additional wiring.
