Simply speaking, switching power supply is indeed a transformer, to transfer the AC 220V to DC voltage which electrical products need. For example, DC 5V for mobile phone, 9V for router, 12V for STB. To get the purer DC voltage, rectification voltage, filter and protection circuit is necessary.
Compare to municipal 220V, low voltage DC which switching power supply transfers is much safer. Owing to the DC voltage switching power supply provides, we can use the electrical products with less risk. Let’s have a look at the usage of switching power supply.
