摘要

This invention refers to modular generators to output bipolar or unipolar voltage pulses with corrected pulse voltage decay and respective process. The pulse correction and the respective process are integrated in p modules, of the n+p generator modules, using power semiconductors (24A), (24B), (25), (26A), (26B), (27A), (27B), (28A), (28B) and (29). The n+p generator modules contain power semiconductors with turn-on and turn-off capability (1A), (4A), (6A), (7A), (8A), (14A), (16A), (17A), (18A), (24A), (26A), (27A), (28A) and non controlled power semiconductors (IB), (2), (4B), (5), (6B), (7B), (8B), (9), (14B), (15), (16B), (17B), (18B), (19), (24B), (25), (26B), (27B), (28B), (29). The n+p generator modules are supplied from a constant voltage source Vdc (11) and apply to resistive, inductive or capacitive loads (12), bipolar or unipolar voltage pulses with amplitude nVdc, being Vdc the no load voltage of capacitors (3), (10), (13), (20), (30). The p modules use variable frequency pulse width modulation and filtering inductor Lf (31) and capacitor Cf (32) to correct the voltage decay of the pulse plateau.
