| description | The invention belongs to the technical field of centralized control power supplies, and particularly relates to a high-power multi-path constant-current centralized control power supply. A control method of the high-power multi-path constant-current centralized control power supply comprises the steps that each path of surge suppression circuit comprises a filter and a capacitor and is used for preventing a clutter and a surge voltage of an external electric part from entering the power supply, and due to high-speed conduction and cut-off of a switching tube inside the power supply, generated strong electromagnetic harmonic radiation is prevented from interfering with an external power supply, and a backward flowing noise voltage to the outside is reduced; meanwhile, the starting impact current is reduced by utilizing the effect that the filter can prevent the current from rising instantly; and each rectification filter circuit comprises a rectifier bridge and an energy storage capacitor.
