A reverse pulse rectification type power supply for plating and a current control method thereof are provided to minimize power loss by supplying a current to a target to be plated as a pulse type. A power supply unit for plating comprises a rectifier(10), a main electric current circuit(20), and a pulse controller(40). The rectifier converts AC power into DC power source, and the main current circuit converts power from the rectifier into pulse power and applies it to a load(30). The main electric current circuit outputs a forward current and a reverse current by the pulse controller alternately. The pulse controller modulates a high speed pulse in the forward current and the reverse current by a PWM control.
