It also has EMC compliant parts, allowing it to be used in a variety of commercial applications. Its compact size and low profile make it easy to integrate into small and tight spaces, and its low weight of 1.53 pounds reduces the overall weight of power supplies.

Working Principle of the ZWS300BAF48/L

The ZWS300BAF48/L uses a non-isolated Buck topology to convert the AC voltage from the power grid to a DC voltage. This involves the use of an inductor, a capacitor and a transistor switch which are linked together in an oscillating circuit. When the transistor switch is closed, a current creates a magnetic field around the coil which induces a voltage across the coil and charges the capacitor. When the transistor switch is opened, the current is stopped and the charge stored in the capacitor is discharged to the load. The voltage across the coil then decreases, creating a secondary magnetic field that collapses and induces a voltage in the opposite direction.

The oscillating circuit causes the voltage across the capacitor and the voltage across the load to be in step with each other. This continuous cycle of charge and discharge creates a DC voltage that is regulated by adjusting the frequency of the oscillation. The ZWS300BAF48/L uses a control circuit to pulse the transistor switch and optimize this frequency accordingly to maintain a constant output voltage.

Conclusion

The ZWS300BAF48/L AC DC converter is a non-isolated Buck step-down converter that can be used in a wide variety of applications. Its wide voltage input range, efficient design and compliant parts make it suitable for industrial, mobile power supplies, automotive, solar power, LED lighting, medical equipment and server/VoIP applications. The ZWS300BAF48/L uses an oscillating circuit with a control circuit to pulse the transistor switch and convert the AC voltage from the grid into a regulated DC voltage.
