1. the current transformer of a modularized multiple constant current output, comprise N submodule, and each submodule includes:

  • a transformer T2N, a N rectifier and an output dc filter capacitor CON, and the transformer primary side winding in each submodule is connected successively;

    It is characterized in that, this current transformer has two-layer configuration;

    wherein the first order comprises the first transformer T1, is connected in parallel on the controlled high-frequency ac source Vac at the first winding two ends, the former limit of transformer T1;

    The second level comprises an aforementioned N submodule;

    The two ends of described T1 secondary winding are connected to respectively the head and the tail two ends of the submodule transformer primary side winding of series connection successively;

    Described constant current output is by the electric current on the interstage exchange bus of secondary winding one end of sampling the first transformer T1, and as the input control input AC source Vac of output constant current control circuit, thereby realization is to the control of each road output current.
