This type of linear power supply has an extremely simple circuit consisting of a transformer ... the rectifier turns it into a rough DC, and the capacitors filter the DC to remove as much AC ...

A power tip that discusses how to address highly integrated USB PD charger design constraints with a self-biasing circuit.

A transformerless power supply (TPS ... This is a handy feature of the TPS circuit. Since the capacitor passes some current as long as the DC voltage doesn’t exceed the AC peaks, you can ...

A system that converts AC current from the wall outlet into the DC currents required by electronic circuits. A computer power supply converts AC into multiple DC voltages. For example, 12 volts is ...

and the power adapter is the external part of the power supply for a laptop. The additional DC voltages are created by internal circuits. Desktop computer power supplies are in one internal unit ...
