Abstract:
    This invention discloses a signal compensation method for passive signal isolators, which adds a compensation transformer in the passive signal isolator circuit, in which, the primary of which is serial to the primary or secondary of the primary transformer in the circuit, one end of the secondary of which is connected with a down-lead to increase the direction of the output current to be connected according to the function of the compensation transformer after passing through the ring magnetic core of the primary transformer and the turn number ratio of the primary and secondary coils of the compensation coils is got by the necessary error compensation, which can increase the field strength by 1/n times of the primary transformer when the secondary coil of the compensation one passes through the ring core of the primary one, so that the isolation transmission of signals can get the compensation by 1/n times.
