A high switch peak voltage is a disadvantage of the
class E amplifier in some applications. A lossless voltage clamp
method with a transformer and a diode has been proposed as a
remedy for the high peak switch voltage. However, this circuit
suffers from a large ringing due to the transformer leakage
inductance, which is superimposed on the clamped voltage and
partially eliminates the effect of the voltage clamping. In this
paper, a switch voltage clamping using a transmission-line
transformer is proposed to reduce the ringing. The proposed
concept was verified with an experimental voltage-clamped Class
E amplifier at 4 MHz and 2.9 W. |
