The filter capacitors selected should be designed to minimize losses in order to be able to dissipate the increased power generated by the harmonic currents. The increased peak voltage, caused by harmonic voltages superimposed on the fundamental waveform, should be examined as part of the design process.
AC Filter Capacitors In DC to AC conversion applications, additional AC filter capacitors are used to reduce high ripple currents from switching devices such as IGBTs. These capacitors are not designed to handle high surge voltages.
This filter is divided into two – a capacitor filter and a L-section filter. The capacitor C1 does most of the filtering in the circuit and the remaining ripple os removed by the L-section filter (L-C2). C1 is selected to provide very low reactance to the ripple frequency.
Switched-capacitor filters are clocked, sampled-data sys-tems; the input signal is sampled at a high rate and is pro-cessed on a discrete-time, rather than continuous, basis. This is a fundamental difference between switched-capacitor fil-ters and conventional active and passive filters, which are also referred to as “continuous time” filters.
Aliasing: Switched-capacitor filters are sampled-data de-vices, and will therefore be susceptible to aliasing when the input signal contains frequencies higher than one-half the clock frequency. Whether this makes a difference in a partic-ular application depends on the application itself.
For robust AC filter capacitor performance throughout the component’s lifetime, an operation voltage derating should be applied if the capacitor is intended for continuous operation, herein defined as uninterrupted connection to the mains for 24 hours per day for several years.
