1. a) Circuit arrangement, for producing eroding pulses in a spark erosion system from a direct voltage source (1) without connected ballast resistors, having : b) at least two circuits (2A, B) arranged in parallel with one another and with the spark gap (3), wherein c) each circuit (2A, B) has in serie : c.1) a first switch (21A, B) linked to one terminal of the direct voltage source (1) ; c.2) a primary winding of a transformer (23A, B) ; and c.3) a second switch (22A, B) coupled to the other terminal of the direct voltage source (1) without interconnection of a discrete energy store, and d) a controlling system (4) arranged for the supply and adjustable and/or controllable time allocation of control signals (A, a, B,b), the control outputs of the control system being coupled to the first and second switches (21A, B, 22A, B) characterized in that e) the first switch (21A, B) is also linked to the primary winding without interconnection of a discrete energy store.
