4. AVOID using a Lab Benchtop programmable DC as the load for the category 3 device up the voltage of this supply when instructed to power up the board, board. These loads have low control bandwidth and will cause the EPC9113 system to instead simply turn on the supply. The EPC9509 board includes a pre- oscillate at a low frequency and may lead to failure. - Page 6 DC output Coil Source Coil Device Board Figure 4: Basic schematic of the A4WP Class 3 source coil Figure 5: Basic schematic of the A4WP Category 3 device board | EPC – EFFICIENT POWER CONVERSION CORPORATION | WWW.EPC-CO.COM | COPYRIGHT 2017...
