Working Principle

The JWS30012 uses a switch-mode topology to convert AC power to DC power. This is done through the use of an input transformer, an inductor, and a switching transistor. First, the transformer takes a voltage input from the wall and converts it to a lower voltage. This lower voltage is then sent into an inductor, where it is further reduced. The reduced voltage is then connected to a switching transistor, which controls the output. This step is repeated several times until the desired output voltage is achieved.

The switching transistor creates high frequency pulses that are used to switch the inductor, thus creating an AC voltage. This AC voltage is then sent to a rectifier, which converts it to a DC voltage. The rectifier is followed by a filter, which removes any remaining AC ripple, thus creating a clean DC voltage. This DC voltage can then be used to power a variety of electronic systems.

Conclusion

The JWS30012 is a single output AC DC converter that provides up to 300 W of power. It features a universal AC input range of 85–265 VAC and has an efficiency of up to 92%. It is widely used in many industrial applications, from medical equipment to consumer electronics. The working principle of the JWS30012 revolves around the use of an input transformer, an inductor, and a switching transistor to convert AC power to DC power. The small size and high efficiency make the JWS30012 an ideal choice for a variety of applications.
