An electrical circuit linking the components in a manner where the current passes through every element consecutively, forming an end-to-end connection is called a series connection. In this type of connection, the current is uniform across all components. Series connections are frequently used to increase the voltage in a circuit. For example, a series connection of multiple batteries can be used to create a higher-voltage battery.
Series Connection in Solar Panels
To meet the minimum operating requirements of the inverter, solar panels are connected in series to increase the voltage. Solar panels are connected in series, with the positive terminal of one panel linked to the negative terminal of another. This arrangement boosts the voltage of the solar system.
Series Connection in Inverters
A series inverter is a type of inverter circuit where the commutating elements L (inductor) and C (capacitor) are connected in series with the load, creating an under-damped circuit. This type of circuit is commonly referred to as a load-commutated or self-commutated inverter.
Series Circuit Example
Series circuits are also used in many other applications, such as alarm systems, toys, and calculators. Some more examples of series circuits in everyday life are as follows.
- Holiday lights: The light bulbs in a string of holiday lights are connected in series.
- Flashlights: The batteries in a flashlight are connected in series, giving higher voltage to the bulb, making it brighter.
- Smoke detectors: Series connection in batteries ensures that the smoke detector will keep working even if one battery dies.
- Car batteries: The cells in a car battery are connected in series to provide maximum voltage to its electrical system.
