DASY8 Module WPT

magpy system 02 androidPicture showing SPEAG’s DASY6 Module WPT. It’s successor, DASY8 Module WPT, will be released in February 2021.

DASY8 Module WPT is based on the MAGPy technology integrated in our DASY8 product line for high precision robot-based evaluations. It is the only system for demonstrating compliance of wireless power transfer (WPT) devices according to the latest draft of IEC/IEEE 63184 PAS (Chapter 8 "Measurement and numerical combination methods") and enables fully automated compliance testing.

System

DASY8 Module WPT is composed of the isotropic probe MAGPy-H3D, the reference amplitude and phase probe (MAGPy-RAφ), and the data acquisition system (MAGPy-DAS) mounted to the DASY8 robot via the emergency stop (MAGPy-ES). The induced electric (E-) fields and specific absorption rate (SAR) are assessed with Sim4Life’s Quasi-Static EM Solver (P-EM-QS) using only the measured data. The dedicated graphical user interface (GUI) fully automates the testing workflow. 

Applications Laboratory evaluation of WPT systems and any other local electromagnetic source not requiring magnetic (H-) field volume scans exceeding 2000 x 1000 x 1500 mm:
  • Evaluation of H-field (3 kHz – 10 MHz)
  • Demonstration of compliance (3 kHz and 4 MHz) according to IEC/IEEE 63184 PAS
Typical Workflows for Compliance Testing 

Basic Restrictions:

  • Probe alignment
  • Teaching the device under test (DUT) position
  • Verification using the appropriate verification sources
  • 3D scan with automated grid optimization
  • Vector potential reconstruction (Sim4Life)
  • Solving the P-EM-QS equation in the muscle half-space
  • Applying coverage factors (pre-determined by the IT'IS Foundation)
  • Advanced evaluations in various posed Sim4Life Virtual Population (ViP) phantoms

Reference Levels:

  • Probe alignment
  • Teaching the DUT position
  • Verification using the appropriate verification sources
  • H-field scans: line (1D), area (2D), volume (3D), arbitrary surfaces (max volume for TX2-90XL: 2000 x 1000 x 1500 mm)
  • Export of H-field data (total, x,y,z): in time or frequency domain
