Take LLC switching power supply system of fan control by temperature change

The utility model discloses a take LLC switching power supply system of fan control by temperature change, including primary input port and vice limit output, control connection carries out between primary input port and the vice limit output to realizing the voltage fluctuation of the vice vice limit of limit output automatically regulated output, still including fan control by temperature change return circuit, and satisfy high low temperature through all selected materials, through long -range voltage compensation, flow equalize, high temperature protection realizes that the product satisfies extreme condition's function. In this way, the utility model provides a take LLC switching power supply system of fan control by temperature change realizes separation of human - machine under the adverse circumstances, maintenance cost under the greatly reduced adverse circumstances with promote the security, through distal end voltage compensation, can realize that the power and the distal end of equipment separate,
