Abstract
Abstract -- Fundamental harmonic analysis (FHA) model is widely used for wireless power transfer (WPT) due to its physical insight and compact form ( exemplified by the tight expression 8RL/π2 for diode rectifier equivalent resistance.) of diode rectifier equivalent resistance. However, it is essential to note that this representation is exclusively valid for Continuous Conduction Mode (CCM), and resonant tank parameters such as inductance and capacitance are independent of equivalent resistance when designing these parameters based on the double-sided LC (DS-LC) FHA model, the selected optimal parameters may not satisfy the CCM prerequisite, which will result in deviations of actual system characteristics, notably affecting output voltage and power predictions from the FHA model. Therefore, the initial optimal design is invalid, and the designers need to execute a circular strategy: namely, designing resonant tank parameters based on the FHA model, then judging or simulating whether it satisfies CCM operation, and if it does not meet CCM, the parameters need to be redesigned.
To ensure that the system always operates smoothly in CCM, a DS-LC parameter design method based on CCM is proposed by analyzing the relationship between the resonant parameters and the load. The effectiveness of the proposed parameter method is verified by simulation.
