strömförsörjningsenhet
A strömförsörjningsenhet, often translated as power supply unit or PSU, is a fundamental component in most electronic devices. Its primary function is to convert the incoming electrical power from a source, such as a wall outlet, into a form that the specific device can utilize. This conversion typically involves transforming alternating current (AC) from the mains into direct current (DC) at various voltage levels required by the internal circuitry.
The process within a strömförsörjningsenhet usually includes several stages. First, a transformer steps down the high
Strömförsörjningsenheter come in various forms, from small, integrated circuits within a smartphone to large, modular units
