The invention relates to a modular, variable electronic power system for generating unipolar or bipolar electrical pulses and the associated uses thereof. Said system comprises one or more electrical pulse generation modules (2) connectable in series； a charging unit (1) for the pulse generation modules (2)； and a control unit (3) for the generation modules (2) and the charging unit (1). Advantageously, each generation module (2) comprises an AC/DC rectifier (8) and a DC/AC inverter (9) connected to said AC/DC rectifier (8) in a bridge configuration for generating bipolar electrical output pulses or pulse trains. Likewise, the charging unit (1) comprises a DC/DC step-up converter (6) connected to an indirect DC/AC inverter (5). The system of the invention provides, at the same time, high versatility for adaptation to different applications, and high values in its output voltage and current levels.
