80W Switching Mode Dc Power Supply

Hello and welcome to another Kikusui Electronics Youtube video. Today I'm going to discuss the two major types of DC power supply and the pros and cons of each. There are two main designs for DC power supplies: linear DC power supplies and switching DC power supplies. To represent each type I have the PWR-01 switching power supply and the PMX-A linear DC power supply. Although both of these instruments are designed to supply DC power to electrical and electronic circuits, the way in which the power is provided is completely different. Linear power supplies like the PMX-A utilize a transformer to drop voltage from the AC line to a much lower AC voltage then use a series of rectifier circuitry and filtering processes to produce a very clean DC voltage. On the other hand, switching DC power supplies regulate output voltage through a process known as pulse width modulation. This process gen
