Abstract:
    This invention relates to a method for increasing reliability of a driving circuit and a large power drive circuit, which takes the common joint of a power amplifying device and a voltage sample feedback circuit as a virtual place in a large power drive circuit of a current-driven load to be connected with a joint place of a signal amplification and matched conversion circuit, in which, the negative end of the supply of the signal amplification and matched conversion circuit is also connected with said virtual place, thus, the output signals of which circuit join into the input end of the power amplification device and signals from the load is only related to the signals coming from the amplification and matched conversion circuit so as to eliminate the interference of sample signal voltage.
