DC DC Converters - UWR-12/420-D24-C Application Field and Working Principle

DC-DC converters are an important component in the power supply chain. They are used to convert the voltage of an output device into a suitable level for the input device. In general, they are capable of converting any type of voltage, from low to high, depending on the specific application. The UWR-12/420-D24-C is one type of DC-DC converter that is designed to convert 12 volts to 24 volts.The UWR-12/420-D24-C DC-DC converter is composed of three parts: the input stage, converter stage, and output stage. The input stage includes a full-wave rectifier, PWM controller, voltage regulator, and over-voltage protection circuit. The converter stage includes an inductor, MOSFET, and Schottky Diode, while the output stage includes a smoothing capacitor and low-dropout linear regulator. The purpose of each component in the converter will be discussed in the following sections.

Input Stage

The input stage is the starting point for the converter, and is used to receive and condition the voltage from the source. The input voltage is first rectified and then regulated using a voltage regulator. A PWM controller is also used to maintain the output voltage by supplying the correct voltage to the converter stage. Meanwhile, an over-voltage protection circuit is used to protect the system from potentially damaging input voltage spikes, by disconnecting the input current when necessary.

Converter Stage

The converter stage is where the voltage conversion happens. An inductor is used to absorb energy from the input voltage and releases it at the output in a continuous flow. A MOSFET is used to quickly switch the current from the input to the output, while a Schottky Diode is used to prevent backflow of the energy.

Output Stage

The output stage is where the power is stabilized and regulated. A smoothing capacitor is used to filter any residual noise in the output voltage before it is released. Finally, a low drop-out linear regulator is used to further regulate the output voltage, ensuring that the output voltage remains constant despite any variations in the input voltage.

Conclusion

The UWR-12/420-D24-C DC-DC converter is a compact and efficient device for converting 12 volts to 24 volts. Its input stage includes a full-wave rectifier, PWM controller, voltage regulator, and over-voltage protection circuit. The converter stage contains an inductor, MOSFET, and Schottky Diode, while the output stage includes a smoothing capacitor and low-dropout linear regulator. By using these components in combination, the UWR-12/420-D24-C is able to accurately and reliably convert 12 volts to 24 volts.
