Power Transfer
Stage
Figure 29. Wireless Power Startup Flow Diagram
Once the startup procedure has been established, the Rx will enter the active power transfer stage. This is
considered the “main loop” of operation. The Dynamic Rectifier Control algorithm will determine the rectifier
voltage target based on a percentage of the maximum output current level setting (set by K IMAX and the ILIM
resistance to GND). The Rx will send control error packets in order to converge on these targets. As the output
current changes, the rectifier voltage target will dynamically change. As a note, the feedback loop of the WPC
system is relatively slow where it can take up to 90 ms to converge on a new rectifier voltage target. It should be
understood that the instantaneous transient response of the system is open loop and dependent on the Rx coil
output impedance at that operating point. More details on this will be covered in the section Receiver Coil Load-
Line Analysis. The “main loop” will also determine if any conditions in Table 4 are true in order to discontinue
power transfer. See Figure 30 which illustrates the active power transfer loop.
