Conducted electromagnetic emissions (EME) and efficiency of strongly coupled magnetic resonance wireless power transfer (WPT) systems with double-slope modulation signals are studied in details using simulations. It is shown that WPT systems with double-slope ramp modulation waveforms compared to WPT systems with conventional ramp modulation waveforms have slightly higher efficiency and appreciably lower conducted EME levels. In order to get maximum EME suppression when double-slope modulation waveform is used optimum value of a parameter controlling slopes of a ramp signal should be found.
