This paper proposes a new circuit topology of single phase AC to DC Series-Parallel Current Injection Resonant Converter (SPCIRC) with wireless power transmission function. Thus, characteristics are accomplished such as shaping the current waveforms of the sinusoidal line with improved power factor resulting in small total harmonic distortion (THD). This is implemented by employing the resonant conversion technique, involving two active soft switches that generate high frequency currents. The circuit operation is explained and the analysis of the converter is presented. The full detailed circuit simulation is then carried out to ascertain the workability of the converter and its ability to operate with wireless power transmission. As a result, a low input current THD of 3.52% was obtained with 130V output DC voltage when supplied by 240V AC input voltage. The efficiency of the proposed SPCIRC is calculated as 87.5%. The current injection topology's main operation is described in detail. © Published under licence by IOP Publishing Ltd.
