Abstract: One of the purposes is to provide a pulse discharge power supply for use in generating pulse discharge. The pulse discharge power supply includes a pulse generation unit, a control circuit, an electric current detector and an electric current signal processing unit. The pulse generation unit generates a first pulse, and applies it to a discharge load for generating pulse discharge. The electric current detector detects an electric current flowing into the discharge load in accordance with the application of the pulse. The electric current signal processing unit outputs into the control circuit a signal based on an integration result of the electric current having been detected. The control circuit controls the generation of a second pulse in the pulse generation unit based on the signal being received.
