It analyzes the contribution of phase-shifted control in IPT power flow control by giving the function expression between the system power and the phase-shift angle in detail. Moreover, a testing platform based on TI F2810 DSP was used to realize a practicality experiment and some experimental waveforms are presented. Finally, the result of the experiment is compared with the theoretical analysis to verify the given IPT system power flow control solution.
