This article presents a parameter recognition-based impedance tuning method for the mismatch caused by capacitance drift and coil misalignment in series–series-compensated wireless power transfer (WPT) systems. First, recognition is proposed to identify unknown parameters of resonant circuits only measuring rms values currents. No phase detection auxiliary measurement coils are required. Furthermore, according recognized parameters, reactance on both sides minimized simultaneously regulating...
This article proposes a mode-switching-based phase shift control (MS-PSC) for wireless power transfer (WPT) systems, which is able to achieve regulation, load matching, and wide ZVS operations simultaneously without using additional dc–dc converters. Based on the mode transitions between full-bridge, mixed-bridge, half-bridge modes of both inverter rectifier, MS-PSC method guarantees wide-range with minimized circulation reactive power. Therefore, system efficiency improved over wider range...
This article introduces a three-mode variable-frequency zero-voltage switching (ZVS) modulation method for the four-switch buck+boost converter. makes this circuit concept well suited applications, such as wireless power charging of electric vehicles, where operates buffer between resonant converter and battery with function to implement required profile. Herein, operation is subdivided into three operating regions according static voltage gain, i.e., buck-, buck-boost- boost-type modes. A...
It is ideal for the wireless power transfer (WPT) systems to operate at resonance state better transmission performance. In practice, however, parameters of resonant circuits often deviate because capacitance drift and coil misalignment. To this end, paper proposes a new parameter estimation method WPT systems, which able facilitate flow control active impedance tuning under deviations. Distinct from traditional identification methods, proposed implemented with an short-circuited rectifier,...
