A Quasi Sliding Mode Output Control for Inductively Coupled Power Transfer System

Yue Sun, Xiao Lv, Zhihui Wang and Chunsen Tang

This study presents a quasi sliding mode output control strategy based on feedforward compensation in an improved Inductively Coupled Power Transfer (ICPT) system. In order to reduce the loss of semiconductor switches, a high frequency transformer has been introduced to change the impedance. To increase the efficiency of system, the output voltage is regulated by shifting phase of the gate signals. The quasi sliding mode control function is established by combining feedforward compensation to offset the impact of load disturbance. Computer simulation and practical experiment are conducted to verify the stability and performance of the proposed control system to ensure the control strategy is effective for ICPT systems.
