A pulse generator arrangement comprising: a plurality of switched pulse generator sections (22; 22A-E); each of said plurality of switched pulse generator sections (22; 22A-E) having an input for receiving a supply of power; each of said plurality of switched pulse generator sections (22; 22A-E) having an output intended for providing voltage pulses to a transformer arrangement; a switch control, being connected to said plurality of switched pulse generator sections (22; 22A-E), characterized in that said switched pulse generator sections are solid-state switched pulse generator sections (22; 22A-E), electronically controllable at turn-on and turn-off; wherein said switch control being configured for providing control signals for turning on and turning off said plurality of switched pulse generator sections (22; 22A-E); said switch control being arranged to provide control signals for turning on switched pulse generator sections of a first subset (25A-F) of said plurality of switched pulse generator sections (22; 22A-E) at a first time instant and control signals for turning off said switched pulse generator sections of said first subset (25A-F) of said plurality of switched pulse generator sections (22; 22A-E) subsequent to said first instant, and to provide control signals for turning on switched pulse generator sections of a second subset (25A-F) of said plurality of switched pulse generator sections (22; 22A-E) at a second time instant, at the earliest simultaneous to said turning off of said switched pulse generator sections of said first subset (25A-F), and control signals for turning off said switched pulse generator sections of said second subset (25A-F) of said plurality of switched pulse generator sections (22; 22A-E) subsequent to said second instant, said second subset being different from said first subset. a plurality of switched pulse generator sections (22; 22A-E); each of said plurality of switched pulse generator sections (22; 22A-E) having an input for receiving a supply of power; each of said plurality of switched pulse generator sections (22; 22A-E) having an output intended for providing voltage pulses to a transformer arrangement; a switch control, being connected to said plurality of switched pulse generator sections (22; 22A-E), characterized in that said switched pulse generator sections are solid-state switched pulse generator sections (22; 22A-E), electronically controllable at turn-on and turn-off; wherein said switch control being configured for providing control signals for turning on and turning off said plurality of switched pulse generator sections (22; 22A-E); said switch control being arranged to provide control signals for turning on switched pulse generator sections of a first subset (25A-F) of said plurality of switched pulse generator sections (22; 22A-E) at a first time instant and control signals for turning off said switched pulse generator sections of said first subset (25A-F) of said plurality of switched pulse generator sections (22; 22A-E) subsequent to said first instant, and to provide control signals for turning on switched pulse generator sections of a second subset (25A-F) of said plurality of switched pulse generator sections (22; 22A-E) at a second time instant, at the earliest simultaneous to said turning off of said switched pulse generator sections of said first subset (25A-F), and control signals for turning off said switched pulse generator sections of said second subset (25A-F) of said plurality of switched pulse generator sections (22; 22A-E) subsequent to said second instant, said second subset being different from said first subset.
