siirtymävirtausta

Siirtymävirtausta, also known as transition current, refers to the temporary current that flows when a circuit is switched on or off. This phenomenon is a result of the inductive and capacitive elements in the circuit. When a switch is closed, the inductive elements, such as coils and transformers, resist the sudden change in current, causing a temporary increase in voltage and current. Conversely, when a switch is opened, the capacitive elements, such as capacitors and inductors, resist the sudden change in voltage, causing a temporary decrease in current. This transition current can be significant and may cause damage to the circuit or connected devices if not properly managed. To mitigate the effects of transition current, various techniques such as snubber circuits, crowbar circuits, and soft-switching techniques are employed. These methods help to limit the peak current and voltage, ensuring the safe and reliable operation of the circuit.
