Power Supply Types | What are the Different Types of Power Supplies?
Linear Power Supplies. A linear power supply is, in many ways, the classic choice. It operates by taking the input voltage, and then, through a combination of transformers, diodes, and filters, provides a steady, direct current (DC) output. The process, however, can lead to some energy loss in the form of heat.
