Bipolar Duty Cycle Control for Dual Side LCC Compensated Inductive Power Transfer System for Wide Output Voltage Range
This paper proposes a hybrid phase shift control strategy for dual side inductor-capacitor-capacitor compensated inductive power transfer (IPT) system to achieve a wide output voltage regulation range. The first-order harmonic time domain model is used to compute the inverter output voltage. Then, models of system operation in constant voltage (CV) and constant current (CC) modes are developed to analyze the efficiency of the battery charging process. The designed controller loops are validated for a 1 kW MATLAB Simulink model. Results show that a maximum efficiency of 93.80% is achieved at full load conditions, and the proposed control strategy achieves zero voltage switching (ZVS) in more switches than the conventional control method.
