SWITCHING AMPLIFIER |
摘要 |
<p>A switching amplifier including a plurality of switching stages, each having a drive transformer, the primary winding of which is separated from the secondary winding in a manner such that no conductive connection exists between them. The primary windings of each drive transformer is connected by means of controllable switching elements to a supply-voltage source in a push-pull circuit arrangement. The switching elements are controlled by means of a signal converter which converts an analog input signal into at least one pulse sequence which is applied to the control electrodes of the controllable switching elements by means of at least one control transformer having at least one primary winding coupled to the pulse sequence and plural secondary windings coupled to the control electrode of a respective switching element. The output terminals of the secondary winding of the drive transformer are connected to a full-wave rectifier. The push-pull circuit arrangement and the full-wave rectifier enable the switching stages to operate at a power output of virtually 100%.</p> |
