filter capacitors have to handle the ripple and leakage current.Y-capacitors have limitations to consider: Thermal limit for high frequency switching currents, in particular with power electronics with no galvanic insulation or shielde tor cables Leakage current requirements of the application. Sufficient dielectric strength to withs
The word “acceptable” may have different meanings in different situations. The acceptability of a filter design will depend on many inter-related factors, including the amplitude response character-istics, transient response, the physical size of the circuit and the cost of implementing the design.
To prevent changes in the LC filter over frequency, a ceramic capacitor voltage rating of > 150 V is mandatory, 250 V is recommended. Equivalent series resistance (ESR) – the capacitor equivalent AC resistance at a specific frequency causes power losses in the capacitor.
eral rules of arranging capacitors are:Capacitors should be located close to the switch and load, s this limits the ‘hot loop’ area.If possible, use multiple capacitors in parallel rather than using a single large capacitor, as parallel capac tors efectively reduce the ESL and ESR. In this way, the energy c
it requires decreasing capacitance in another.Capacitors can be scale in groups that are independent of one another. Such groups generally exist around opamp-based integrators. Furthermore, scaling all the capacitors connected and switched to the input of an opam leaves the filter transfer function unchanged.Capacitor groups ca
