1000W Wireless Power Transfer System

Technology Overview

An efficient wireless power transfer system, based on proprietary magnetic coupling technology that delivers up to 1 kW of wireless power. It is designed to be maintenance-free and requires the least amount of effort to use.

The wireless power transfer system provides the convenience and safety of electrical charging without cables and human intervention. It can operate in all weather conditions and harsh environments.

Technology Features & Specifications

Magneto-Dynamic Coupling (MDC) is a safe, efficient and low-frequency wireless power transfer technology. It is unique in the space of wireless charging technologies in that it operates through the coupling of two magnetic fields at a much lower frequency ( < 200 Hz) than other competing technologies which operate typically above 20 kHz. Wireless energy transfer is accomplished through magnetic torque rather than electromagnetic field coupling of coils. The benefits are that the system is potentially more efficient (less lossy), smaller, generates essentially no RF interference and can operate in harsh weather conditions.
