The progress in semiconductor design sets the trend in current and future devices of power electronics: it manifests itself particularly in smaller dimensions, as well as in higher voltages and switching frequencies. Referring to intermediate circuit capacitors, this trend leads to aiming at higher energy densities and larger current loads, and – at the same time – decreasing space.
Under these conditions, especially aluminium electrolytic capacitors and plastic film capacitors offer advantageous solutions. Jianghai has both technologies in the production program and this presentation gives an overview on the major differences between aluminium electrolytic capacitors and film capacitors.
