The selection of the number, type, size and location of the capacitors and harmonic filters depends on factors such as harmonic distortion, voltage regulation, power factor, power and energy losses and investment costs.
a large portion of filter size and cost [1-4]. Furthermore, the temperature and reliability limitations of filter capacitors can present a significant design constraint. automotive electro-hydraulic power steering. The input filter for this switching inverter requires three electrolytic capacitors and two inductors. The capacitors account for
Portable electronic devices require high-performance miniaturised electronic components, preferably produced at low cost. In most line-powered applications, alternating current (AC) line filters are used to filter AC lines to direct current (DC) signals, making filtering capacitors a key necessity in modern electronic devices.
