AUTO CURRENT DIVIDING APPARATUS OF AN AUDIO FREQUENCY ELECTRICAL JOINT APPARATUS

摘要

PURPOSE: An automatic current dividing device of an AF non-insulated electrical joint circuit is provided to prevent the overload of one SMPS by uniformly distributing a current according to the number of a SMPS(Switching Mode Power Supply). CONSTITUTION: A SMPS device(50,60) supplies a driving power to a transmitter and a receiver. A current sensor(58) senses the output current of the SMPS device. A switching controller transmits a switching control signal to a current distribution management part(70) in response to the current sense signal of the current sensor. The current distribution management part supplies uniform power to the SMPS device in response to the switching control signal of the switching controller.
