Switching amplifier with an inductor
Abstract:
pa A switching amplifying method or a switching amplifier for obtaining a linearly amplified replica of an input signal, is highly efficient, and does not have the disadvantage of “dead time” problem related to the class D amplifiers. Said switching amplifier comprises: an inductor means; a switching unit for switching a current from a DC voltage to the inductor means; a controllable diodes unit for blocking a current when the current from the DC voltage to the inductor means is switched on, and conducting the current from the inductor means to a filter unit when the current from the DC voltage to the inductor means is switched off; an amplifier control unit to control the switching unit and the controllable diodes unit according to the input signal; the filter unit filtering the output of the controllable diodes unit for getting an output signal.
