Energies 2016,9, 10 transferpowerare thesame. Thenaq-Zsource-basedpowerregulationmethodisproposedtoadjust the charging current online. At last, a 3kWprototypewith~95%efficiencyover a 20 cm transfer distance is implemented to validate our research results. Different shoot-through timedurations determinedifferentchargingcurrentsdespite thesameinputvoltage.Whenthe inputvoltage is set to be200V,a1μsshoot-throughtimecanboost thechargingcurrent from5.26Ato8.26A,anda1.5μs shoot-throughtimecanboost thechargingcurrent from5.26Ato10.2A.Wehopetheworkpresented in thispaper isbeneficial to thedevelopmentofwirelesspower transfersystems.
