Each path includes a resonance tank including a transmit coil coupled with at least one resonance capacitor, a first switch serially coupled with the resonance tank and switching node A of the bridge inverter, a first clamping element in parallel with the first switch, a second switch serially coupled with the resonance tank and switching node B of the bridge inverter, and a second clamping element in parallel with the second switch. A method includes generating a wireless power signal through a used coil in a first parallel path, and clamping a parasitic voltage generated in at least one unused coil in at least one additional parallel path through a clamp element across a switch in the at least one parallel path for the at least one unused coil."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatuses and wireless power transmitters having multiple transmit coils and related method","description":"A wireless power transmitter may include a bridge inverter and a plurality of parallel paths operably coupled to the bridge inverter.
