Abstract: An electrical converter system (10) comprises an electrical converter (12) for converting an input voltage into a converter output voltage (20); a transformer (14) interconnected with the electrical converter (12) at a secondary side (28) and for transforming the converter output voltage (20) into a transformer output voltage (30) at a primary side (32); and a controller (16) adapted for switching the electrical converter (12) with optimized pulse patterns (22), such that the electrical converter (12) produces the converter output voltage (20) with a fundamental frequency and a series of harmonics (24). Between the secondary side (28) and the primary side (32), the transformer (14) has a frequency damping behaviour like a low pass filter. The optimized pulse patterns (22) are optimized such that the converter output magnitudes (26) of harmonics (24) in an upper frequency range (68) are higher than those of harmonics (24) in a lower frequency range (66) and such that the converter output magnitudes (26) of the harmonics (24) in the upper frequency range (68) at the secondary side (28) are higher than predefined threshold magnitudes (36, 36a, 36b) for the harmonics (24) in the upper frequency range (68) and transformer output magnitudes (34) of the harmonics (24) in the upper frequency range (68) at the primary side (32), which are damped by the transformer (14), are lower than the predefined threshold magnitudes (36, 36a, 36b).
