Abstract: A discharge pulse generator for supplying electric power between a pair of electrodes (1, 2) comprises a distributed-constant circuit (8) of a predetermined length with one end connected to the electrode (1, 2), charger means (16) connected of the distributed-constant circuit (8) for charging the capacitor of the distributed-constant circuit (8), rectifier means (13) connected to the other end of the distributed-constant circuit (8) in the direction in which no current flows on the voltage of the charger means (16), and a resistor (10) connected in series to the rectifier means (13) and having a resistance equivalent to the characteristic impedance of the distributed-constant circuit (8). The pulse generator may allow electrical discharge machining to be performed more accurately and quickly.
