Abstract
Transformers () for transforming primary signals into secondary signals comprise primary and secondary parts that comprise boards (--) with turns. By introducing distances larger than zero between for example any pair of neighboring boards (--), parasitic capacitances of the transformers () are reduced, and the secondary signals may comprise relatively fast/high voltage pulses having rise times >1 kV/μsec. To reduce proximity effects and any resulting losses, the primary and secondary boards (--) may be stacked in interleaved ways. Such sandwich constructions reduce leakage inductances. In a particular direction, distances between subsequent primary boards (--) and distances between subsequent combinations of primary and secondary boards (--) are to be increased to further reduce capacitive losses in that particular direction. Relatively low voltage differences may be present between relatively close boards (--), and relatively high voltage differences may be present between boards (--) that are relatively far away from each other.
