Stability Analysis and Efficiency Optimization of an Inductive Power Transfer System With a Constant Power Load

Abstract: Series-series compensated inductive power transfer (SSIPT) systems have been widely studied and characterized for constant resistance loads (CRLs) and constant voltage loads (CVLs), but much less so for constant power loads (CPLs), although CPLs have numerous applications. In this work, we address some of the fundamental knowledge gaps for SSIPT/CPL systems that we believe have not been fully explored in the literature. First, we apply Middlebrook's stability criterion to derive a closed-form impedance-based s… Show more

“…Among these applications, due to advantages such as relatively higher power transfer efficiency, reliability and easy maintenance and management, self-induced methods are most frequently used. [1]~ [3] Wireless low-power transfer systems such as body implant medical devices or kickboards necessitating the use of self-induction require high power density due to system characteristics. Therefore, a large amount of prior research has been devoted to achievement of high-power density-based wireless power transfer through high-frequency switching or configuration changes of Transmitter (TX)/ Receiver (RX) pads.…”

“…οχήματος, όπου ο ασύρματος φορτιστής απορροφά ισχύ από το οικιακό μικροδίκτυο. Σε αυτήν την περίπτωση, η συμπεριφορά του ασύρματου φορτιστή ως προς το μικροδίκτυο αντανακλάται ως φορτίο σταθερής ισχύος με τη συνακόλουθη επίδραση στην ευστάθεια του μικροδικτύου[238]. Στη δεύτερη περίπτωση, όταν οι συσσωρευτές του ηλεκτρικού οχήματος είναι επαρκώς φορτισμένοι και το φορτίο του μικροδικτύου είναι υψηλό, τότε ο ασύρματος φορτιστής εγχέει ισχύ προς το μικροδίκτυο, λειτουργώντας ως μια επιπλέον πηγή σταθερής ισχύος η οποία συνεισφέρει ένα προκαθορισμένο ποσό ισχύος, ανάλογα με τις δυνατότητες και την επάρκεια των συσσωρευτών[108].…”
