Abstract (en)

[origin: DE19756873A1] An electrical circuit arrangement (G) for transforming (W) magnetic field energy (M) into electric field energy (E) has at least one first accumulator element (L) for magnetic field energy (M), a second accumulator element (C) for electric field energy (E), a semiconductor valve element (D) and an electrical switching element (S). According to the invention, the semiconductor material of which the semiconductor valve element (D) is made has a band gap (VB) of at least 2 eV and a breakdown field strength (EK) of at least 5*10 &cir& 5 V/cm. The semiconductor material of which the semiconductor valve element (D) is made contains, in particular, silicon carbide (SiC), gallium nitride (GaN) or diamond (Cdia). The semiconductor valve element (D) is, in particular, a semiconductor diode, preferably a Schottky diode. Owing to the low dynamic switching losses of the semiconductor valve element (D) according to the invention, the electrical circuit arrangement (G) can be used with the smallest components even at high operating voltages and high switching frequencies.
