High voltage Aluminium electrolytic capacitors with working voltages UR > 400 V are the backbone of industrial and automotive electronics. The main application is in the DC-link circuit. The Advantage of those Capacitors are lower cost compared to other capacitor types, a high CV product and a better cool-ability.
Polymer Aluminum Electrolytic capacitors have ca. 10 times lower ESR values as classical Aluminium electrolytic capacitors with liquid electrolyte and are much more temperature stable. So far, they are only available for rated voltages lower than 250 V. It would be therefore favorable to have Polymer Aluminium Electrolytic Capacitors also operating at further higher voltages.
To step forward a new developed breakdown model of classical Aluminium Electrolytic Capacitors will be discussed and first preliminary data of high voltage Polymer Aluminium Electrolytic Capacitors data with rated voltage over 400 V will be presented.
