This paper presents an autonomous polyphase current-fed push–pull resonant converter without the need of monitoring and controlling its phase delays. Although the method is valid for multiple phases, a three-phase system is studied to show that accurate 120° phase shift can be realized by coupling three identical magnetic coils of a resonant converter with zero voltage switching (ZVS). Unlike the...
Today, academic and industrial research is focused on innovative battery charging methods to ensure complete mobility of both handheld devices and electric vehicles. Wireless power transfer is actually the leading strategy even if efficiency related issues are to be solved for a successful marketing. In this paper, a wireless battery charging station is proposed for electric assisted pedal bikes....
