Abstract
This article describes designer's experience with radiofrequency (RF) high
reactive power capacitors problems, which in many cases may be a critical
element for various devices - like ICP plasma torches; SMPS converters;
induction heaters; radio transmitters etc. New materials at the markets
allow to solve the problem that at small capacitance - high voltage - high
amperage combination, capacitors have to withstand circulating reactive
power load from kVAR to MVAR range, hence the value of loss factor tan(?) of
the selected insulator material has a critical role, to minimize
overheating. Few designer strategies are disputed, and convincing
experimental data on selected new industrial materials are presented.
