Their benefits are such that it’s become surprisingly rare to see a traditional linear power supply with a mains-frequency transformer and rectifier circuit, so [ElectroBoy]’s dual voltage PSU ...

Most of these power supplies use a transformer ... power supply, using a series capacitor to limit current. To bring the voltage to an acceptable level, a recognizable bridge rectifier is paired ...

The flyback is a logical choice when choosing a system topology that must generate multiple outputs from a single power supply. Since the voltage across each transformer winding is proportional to the ...

The low cost, simplicity of design and intrinsic efficiency of flyback transformers have made them a popular solution for power supply designs of below 100W to 150W ... of the transformer winding ...
