TDK Corp. has introduced a range of new power capacitors for rated voltages of 1100 V to 2300 V and covers a 465 µF to 2525 µF capacitance range designed for industrial and renewable energy applications.
The B25645A capacitor series. Source: TDK The B25645A capacitor series can be fitted close to IGBT modules. Combined with a low 14 nH self-inductance of the capacitors any substantial voltage overshooting is stopped at the IGBT modules when the current is shut off. Because of this, no snubber capacitors are needed, and the design makes parallel connections of capacitors easy.
The capacitors are cubic in design and available in two versions of either 243 x 169.5 x 90 mm or 258 x 215 x 115 mm.
