Capacitors 301: Choosing Correct Input/Output Capacitor Types and Combinations for Power Converters
Abstract: In this webinar we talk about the need for choosing the correct type of input and output storage & filter capacitors in power converters; what role ceramic and electrolytic capacitor types have in the design, and how the noise on the converter input voltage will change with the varying amount of capacitance. We will show exactly how to calculate the ceramic and electrolytic capacitor type values that are needed for a given specification, specifically calculating how much ceramic capacitance is needed at the input side of the converter to reduce the input voltage ripple to a specified value. Discuss how to calculate the size for the energy storage/bulk electrolytic capacitors including voltage rating and ripple current rating

Capacitors 201 – Capacitor Basics and Technologies the Sequel
Abstract: Capacitors make up two thirds of all electronic components and there is a huge diversity of technologies which can overwhelm young engineers. All capacitors store electrical energy in the electrical field created in a dielectric material and they are used for very diverse applications like voltage stability and filtering. How that works differs between tiny MLCCs and huge electrolytic cells, from pF ratings up to the hundreds of Farads in supercapacitors. In this presentation, we continue the introduction of different capacitor including MLCCs and supercapacitor solutions taking into account the advantages and disadvantages.
