Aluminum - Polymer Capacitors

Introduction

Aluminum-polymer capacitors are a type of capacitor that is constructed with an aluminum heating element, a conducting polymer electrolyte, and two electrodes. This type of capacitor offers many advantages over standard aluminum electrolytic capacitors, such as improved capacitance, high temperature tolerance, longer life, and improved reliability.

870135174003 Application Fields

Aluminum-polymer capacitors are often used in a variety of applications where higher capacitance, higher temperature operation and increased reliability is needed. These include grid-connected power supplies, solar inverters, DC/DC converters, fuel cells, rechargeable batteries, medical devices and aerospace electronics. They are also very popular in automotive applications such as airbags, air conditioning, engine control, and automotive audio systems.

870135174003 Working Principle

The basic principle behind aluminum-polymer capacitors is that they are capable of holding more electrical charge than traditional aluminum electrolytic capacitors. This is because the electrochemically active components of the capacitor layer, the aluminum heating element and the conducting polymer electrolyte, have a much higher capacitance than conventional aluminum electrolytic capacitors.When an electric current is applied, the aluminum heating element is heated, which causes a reaction with the polymer electrolyte to generate an electric charge. This charge then flows between the two electrodes, which are typically made of tantalum, to create an electrical field. This electrical field then produces an electric current in the circuit, and the capacitor stores the charge generated by this current until it is released by the circuit breaker or cut off by the power system.

Conclusion

Aluminum-polymer capacitors are a very useful type of capacitor due to their improved performance capabilities compared to traditional electrolytic capacitors. They are widely used in many applications, such as grid-connected power supplies, solar inverters, DC/DC converters, fuel cells, rechargeable batteries, medical devices and aerospace electronics. They are also increasingly being used in automotive applications due to their improved performance capability. The basic principle behind aluminum-polymer capacitors is that they are capable of holding more electrical charge than traditional aluminum electrolytic capacitors.
