DC-DC converters are devices used to convert one DC voltage source, sometimes referred to as an input voltage, to another, lower-voltage DC output. The UWR-5/2000-D12A-C is an example of such a device, and its application field and working principle is as follows.

Application Field

The UWR-5/2000-D12A-C is a DC-DC converter designed for small space applications, with a 5A/7.1A maximum output current and an operating frequency up to 55kHz. It is well suited for off-line, low-power, high-efficiency and cost-effective applications, such as portable and mobile devices, consumer electronics, and industrial and automotive applications.

Working Principle

The UWR-5/2000-D12A-C works by first converting the input DC voltage to an AC signal using a full bridge DC-DC converter, then rectifying the AC signal to create a DC output voltage. This DC voltage is then fed to a power stage, where it is switched to create a DC voltage that is equal to or lower than the input voltage. This is done by using switching elements to control the power flow in the circuit. The conversion ratio is determined by the duty cycle of the switching elements, which is set by the voltage feedback from the output of the circuit.

The output voltage is then regulated by using a feedback circuit. This circuit samples the output voltage, compares it to the desired voltage using an error amplifier, and then adjusts the duty cycle of the switching elements accordingly. This process is repeated until the desired output voltage is reached.

The UWR-5/2000-D12A-C also features optional special functions such as soft-start and current protection, which can be enabled by setting specific input voltage levels. These functions can be used to protect the circuit from over-current or over-voltage conditions.

Conclusion

In conclusion, the UWR-5/2000-D12A-C is a DC-DC converter designed for small space applications, with a wide range of features and functions designed to make it efficient, accurate, and reliable. It is designed for off-line, low-power, high-efficiency, and cost-effective applications, and features optional special functions such as soft-start and current protection. It works by converting the input DC voltage to an AC signal using a full-bridge DC-DC converter, rectifying the AC signal, and then switching it to create a DC voltage that is equal to or lower than the input voltage, which is then regulated using a feedback circuit.
