Il trasformatore di alimentazione a commutazione is a kind of power transmission or an important part of signal transmission, which mainly uses the principle of electromagnetic induction to transmit power or signal from one circuit to another circuit. When the alternating current passes through the primary coil, an alternating magnetic flux is generated in the iron core (or magnetic core), and a voltage (or current) is induced in the secondary coil. Il trasformatore di alimentazione a commutazione consists of an iron core (or magnetic core) and a coil. Coils have two or more windings. Il winding connected to the power source is called the primary coil and the other windings are called the secondary coil.
Current flows in from the primary coil and out from the secondary coil. If the number of turns of the primary coil is greater than the number of turns of the secondary coil, the voltage on the secondary coil will decrease, which is a step-down low-frequency transformer; on the contrary, if the number of turns of the primary coil is less than the number of turns of the secondary coil, then the secondary coil Il voltage on it will rise, which is called a boost low frequency transformer.
Si noti che qualsiasi trasformatore ad alta frequenza può trasferire energia solo dal primario al secondario. Aumenta o diminuisce la tensione, ma non la potenza. Trasformatori ad alta frequenza primari e secondari
Il ratio of the stage voltages is equal to the ratio of the secondary and primary currents. Disregarding the high frequency transformer loss, it can be said that the primary input power is equal to the secondary output power.
