tehovirtalähteissä
Tehovirtalähteissä refers to power supplies that are designed to convert electrical energy from one form to another. These devices are crucial components in a vast array of electronic systems, ensuring that the voltage and current supplied to circuits are within the required specifications for their operation. They are broadly categorized into linear and switching power supplies, each with distinct operating principles and applications.
Linear power supplies achieve voltage regulation by dissipating excess energy as heat through a transistor acting
Switching power supplies, on the other hand, operate by rapidly switching a semiconductor switch on and off.
