This paper proposes a compact pulse generator for NOx removal application for diesel automotive. The rising time is important factor to increase NOx removal efficiency in pulsed corona discharge method. Manufacturing cost and compactness of the pulse power generator should be satisfied for automotive application. The proposed pulse power uses a low voltage thyristor, a pulse transformer with the function of saturated magnetic switch, and series connected general diodes as opening switch to satisfy that requirements. With 200 resistor load, the experiment results show that the output voltage is 21㎸, the rising time is about 21ns, and the pulse width (FWHM) is about 42ns.
