    摘要: A source for a wireless energy transfer system, comprising: a source resonator (2422); an adjustable power supply; an amplifier (2402) connected to the adjustable power supply and to the source resonator, the amplifier having electronically controllable switching elements (S1, S2); a source amplifier control (2410) configured to control a switching characteristic of the switching elements of the amplifier, wherein a DC voltage of the power supply is transformed to a switching or oscillating voltage via the amplifier and used to drive the source resonator,
    wherein the source amplifier control is configured to control a duty cycle of the switching elements of the amplifier to substantially maintain zero voltage switching, and wherein the source amplifier control is configured to control voltage output of the adjustable power supply by a variable bus voltage to control power output to the source amplifier and power delivered to the resonator.
