DC DC Converters

A DC-DC converter is an electronic device that transforms a direct current (DC) voltage, or power supply, from one level to another. It is used extensively for power conversion, power management and control in a variety of applications, from laptop computers to automotive applications and industrial systems. One particular type of converter, the UWS-5/10-Q48NH-C, is designed specifically for sub-millisecond off-time control in synchronous rectifier power converter systems.

UWS-5/10-Q48NH-C Application Field

The UWS-5/10-Q48NH-C is a high-current, low-frequency, non-isolated DC-DC converter. It is designed primarily for use in single-stage switching converter applications such as switching power supplies and switching amplifiers. It can be used in a variety of applications, including automotive systems, industrial systems, server, datacenter, and IT systems, and medical, sanitary, and home energy storage systems.

UWS-5/10-Q48NH-C Working Principle

The UWS-5/10-Q48NH-C converter operates on a synchronous rectifying principle. The input DC voltage is typically regulated by a switch to the output stage, which rectifies the AC current to DC.High current operation is enabled by the use of a high-current switching diode. The diode is controlled by a control circuit, which is synchronized to the output voltage of the main stage. This feedback ensures that the diode is always in its on-state, as long as current is flowing.The diode is pulled to its lower threshold voltage, and this controls the output current. This voltage is kept constant during operation, and it allows the output current to be increased or decreased quickly and accurately, even for sub-millisecond off-time control.

Advantages of UWS-5/10-Q48NH-C Converter

The UWS-5/10-Q48NH-C converter offers some major advantages compared to other converters on the market. Firstly, its non-isolated design eliminates the need for expensive isolation circuitry. Secondly, its high-current switching diode allows for high current operation at much lower voltages than other converters.This makes it ideal for demanding applications like server, datacenter, and IT systems, as well as for medical, sanitary and home energy storage systems where efficiency is of primary importance. Finally, its synchronous rectifying principle ensures that the output current is accurately regulated, enabling sub-millisecond off-time control.
