EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62969-2 testing. IEC EN 62969-2 specifies procedures and definitions for measuring the efficiency of a wireless power transmission system for automotive vehicle sensors. This standard relates to the power range below 500 mW.
In the concept of a resonant wireless power transmission system, efficiency is a function of the loading conditions (eg light load, medium load and full load) as well as the degree of connectivity between the transmit and receive coils. Automotive vehicle DC supply means that the electrical power supplied by the vehicle can be +12V or +24V. RF generator unit is the circuit that can convert DC power to RF power.
RF coupling efficiency is defined as the transmission efficiency when the signal is transmitted wirelessly. Efficiency is represented by the ratio of RF output power to RF input power. Efficiency can be affected by the coupling between the transfer and the receiver, the loss of resistance between the transfer and the receiver, the radiation. RF coupling efficiency is the main efficiency of the wireless power transmission system.
The RF rectification efficiency is represented by the power ratio of the DC output power to the RF input power received by rectifying the circuit. RF rectification efficiency can be affected by the efficiency of the diodes.
