Control and irregularity of electric power of the switching type power amplifier which had or more the stage of one or two

摘要

The expansion equipment which includes the last amplifying stage which at least has three which includes the input port and the output port and the power source port ports was used, this method to have with the stage which it changes selectively the input signal which at least one of power source output and, in order to control the modulation characteristic of the output signal of the expansion equipment which is made with that output port, you follow to the quality which the output signal of stage and the expansion equipment which modify the signal which is impressed in the power source port of the expansion equipment is desired, is impressed in the input port of the expansion equipment, in amplitude in the method the variable output signal being formed, the description aboveAs for the last amplifying stage, there are no times when it operates timewise between considerable ratio and inside the linear territory, the last amplifying stage there are no times when between two states of hard on state and hard off state, the aforementioned last amplifying stage continually or measures the aforementioned variable output signal frequently with the drive signal which is driven over again, returns adjusts, they feature that it is controlled.
