PFC chokes
A PFC choke (power factor correction choke) is a component in electrical devices that is used to improve the power factor. It reduces the phase shift between voltage and current, thereby increasing the efficiency of the power supply. By reducing the reactive power that is fed back to the power grid, PFC chokes help to reduce overall energy consumption and electromagnetic interference.
They comply with EN 61000-3-2.

KLL chokes
The KLL choke series was specifically developed for use in scenarios that require excellent efficiency and a compact design at the same time. Especially in situations characterized by high ripple currents, this series is characterized by its minimal power loss. This advantage is a result of the low remagnetization losses, which make the use in PFC circuits and in chokes that operate under high DC link voltages particularly efficient.

What are storage chokes and what are they used for?
Storage chokes are electronic components that are used to limit or filter the flow of electrical current. They are used in various applications to reduce unwanted electrical signals, minimize interference or improve the protection of devices.
The main function of a storage choke is to limit the flow of current by increasing the resistance for certain frequencies. This can help to improve the stability of circuits by reducing the current flow in certain frequency ranges.
Storage chokes are often used in switching power supplies to reduce noise and electromagnetic interference (EMI). They help to smooth the current flow and minimize unwanted voltage peaks or drops.
In addition, storage chokes are used in inverters, DC motors, switching networks and other electronic circuits to limit current flow, minimize energy loss and improve efficiency.
Overall, storage chokes are used to control current flow and minimize unwanted electrical signals to improve the performance and reliability of electronic devices.

How do storage chokes work and what role do they play in electrical circuits?
Storage chokes are passive electronic components that are used in electrical circuits to limit or regulate the flow of current. They consist of a coil that is usually wound from insulated wire.
The operation of a storage choke is based on the properties of inductances. When a current flows through the coil, it generates a magnetic field around itself. This magnetic field stores energy. If the current flow is stopped abruptly, the storage choke releases the stored energy in the form of a counter-current.
Storage chokes fulfill various tasks in electrical circuits:
1. current limiting: storage chokes limit the current flow in a circuit by limiting the increase in current. This can be useful to protect circuits and devices from excessive current.
2. filtering: Storage chokes can also be used to filter electrical signals. Due to the inductance of the coil, higher frequencies are attenuated more than lower frequencies. This makes it possible to reduce or remove unwanted high-frequency signals.
3. energy storage: Storage chokes can also be used to store energy in circuits. For example, when a current flow is interrupted, the storage choke releases the stored energy in the form of a reverse current that can be used in the circuit.
In summary, storage chokes play an important role in electrical circuits by limiting the flow of current, filtering unwanted signals and storing energy. They are used in a wide range of applications, from power supplies to switching power supplies and high-frequency circuits.

How can storage chokes be correctly dimensioned and what factors need to be taken into account?
The dimensioning of storage chokes depends on various factors and can vary depending on the application. Here are some important factors to consider when dimensioning:
1. amperage: The storage choke must be able to withstand the required current without overheating or limiting its function. The current depends on the application and should therefore be calculated carefully.
2. voltage: The storage choke must also be able to withstand the applied voltage. The voltage depends on the current source or circuit in which the choke is used.
3. inductance: The inductance of the storage choke determines how strongly it limits the current flow. The higher the inductance, the more the current flow is throttled. The inductance should be selected so that it provides the necessary throttling but is not too high so as not to influence the circuit too much.
4. frequency: The frequency of the current flowing through the choke is an important factor in dimensioning. Storage chokes often have a specific frequency at which they operate most efficiently. It is important to know the frequency of the current and choose a choke that is suitable for this frequency.
5. temperature: The temperature of the circuit in which the storage choke is used must also be taken into account. The choke should be dimensioned in such a way that its function is not impaired even at higher temperatures.
6. space: The space available for mounting the storage choke can also be a factor. It is important to choose a choke that fits into the available space and also provides the required electrical characteristics.
It is advisable to consult an expert or manufacturer when sizing storage chokes with the specific requirements of your application to ensure that the correct choke is selected.
