Continuing the series of webinars for EVSE test solutions, this webinar will review the industrial standards with regards to the WPT (Wireless Power Transfer/Transmission) for EV charging. We will discuss the test requirements of the WPT and provide the associated test solutions with the automatic test systems (ATS) to ultimately validate the functionality and improve the efficiency of EV charging through WPT.
How to Use RF Impedance Measurements to Ensure the Quality of Miniaturized Power Inductors
Most high-frequency and miniaturized power inductors are metal molding-type inductors. The magnetic metal powder surfaces are usually treated with an oxide layer to reduce eddy current losses at high frequencies, enhancing the usable frequency range and reducing losses and temperature rising. However, users typically cannot determine the particle size of the magnetic material and the integrity of the oxide layer after molding and sintering through visual inspection alone.
