Abstract:
A high efficiency voltage mode class D amplifier and energy transfer system is provided. The amplifier and system includes a pair of transistors connected in series between a voltage source and a ground connection. Further, a ramp current tank circuit is coupled in parallel with one of the pair of transistors and a resonant tuned load circuit is coupled to the ramp current tank circuit. The ramp current tank circuit can include an inductor that absorbs an output capacitance COSS of the pair of transistors and a capacitor the provides DC blocking.
