| Summary: | This paper proposes a novel single-phase AC to DC Series-Parallel Current Injection Resonant Converter (SPCIRC) circuit topology with wireless power transfer function. Consequently, low total harmonic distortion (THD) of the controlled sinusoidal line's current waveforms with increased power factor resulting are achieved. This is accomplished using the resonant conversion method, which entails the use of two active soft switches that create high frequency currents. Nevertheless, this paper emphasizes the analysis of the normalized harmonics amplitude in conjunction with the modulation index selection, in order to produce the steady-state equation of the SPCIRC. The steps involved are explained in detail in a flowchart, and the results are plotted in graphs. The results obtained show that the normalized harmonics amplitude characteristics of different switching frequencies are indistinguishable. The polynomial equation of 120 kHz plot is used to produce the steady-state equation of the SPCIRC. The circuit operation is explained, and the analysis of the plot is presented. © 2023 IEEE.
