Application Field and Working Principle

Aluminum electrolytic capacitors are used in wide range of electrical applications. In general, they are used to store energy and improve power factor. EDH685M050A9DAA aluminum electrolytic capacitor is used in many power electronic applications such as switching power supplies, inverters, converters, DC-DC power suppliers, motors drives and renewable energy systems. This capacitor also can be used to filter ripples, improving the stability in power supply.

The working principle of aluminum electrolytic capacitor can be described as the combination of a capacitor and an electrolytic cell. The component consists of a rolled-up aluminum foil as the anode and a separator which is soaked in a liquid electrolyte as the cathode. The electrolyte is a solution of anionic molecules, forming an alternate-layer structure between the two electrodes. When voltage is applied, ions from the electrolyte move towards the anode and get trapped in the anode’s porous surface, forming a solid layer of oxide. Thus, a current is created and capacitance is created. The capacitance of the component is determined by its size and the thickness of the oxide layer.
