A capacitor can be defined as a primary storage device used for storing electric charges in an electric field, and capacitors tend to release them whenever required. Every electronic device that we use in our day-to-day life needs a capacitor for functioning, as it serves many applications.
Applications of Capacitors
Capacitors are used in different ways to perform different functions according to the circuit of the device. There are many types of capacitors available, which have different values, large value range or maybe small value range. There is another variety of capacitors that may have different current capabilities, different stability levels, and maybe higher temperature coefficient states. For any electrical circuit, an appropriate capacitor is chosen for better functioning. These are the following applications of capacitors-
Energy Storage- Storage of electrical energy is the first and the main application of a capacitor. It is performed when the capacitor is connected to an electric circuit. If suddenly the circuit gets disconnected from the capacitor, even then, the capacitor has the tendency to consume that stored amount of energy and work as a temporary battery. In case when batteries are changed in an electronic device, capacitors are used to control the power supply. It helps in the prevention of the loss of data.
Pulsed power and weapons- The construction of capacitors are made with low inductance and high voltage functions to complete electric current levels for pulsed powered devices. Pulsed powered devices are those, which usually hold electromagnetic gadgets, generators, pulsed lasers, and particle accelerators.
Power conditioner- Capacitors perform the functions of power conditioning, which is used for supplying power to ease the outcome of a complete or halfway rectifier. Capacitors also perform the functions of charging pump circles, as they generate high voltage. In any electronic device, a DC power circuit is connected with the capacitor in parallel to produce smooth current fluctuation for the signal.
Correction of power factors- In any electronic device, power supply distribution is done through capacitor power factor correction. The capacitor units are measured as reactive power in the VAr unit. It is done to prevent inductive loading in appliances.
Safety of capacitors- Capacitors hold a large amount of energy, which must be controlled with all the precautionary measures; otherwise, it could be dangerous. The high energy level can build electrical shocks, and even the equipment can be destroyed if the capacitor gets disengaged.
RF coupling and decoupling- The RF coupling and decoupling is done in the same way as the capacitors, regular coupling and decoupling. But for RF applications, capacitors should have appropriate RF performance. For low-frequency capacitors, operations may be different.
Smoothing capacitors applications- They are just like decoupling capacitors, and they are used usually in conjunction with a power supply. When the line signal is received from a transformer and a rectifier, the received waveform is not always smooth. It can range from zero to peak(endpoint).
