DC DC Converters

DC DC converters, also known as DC to DC power converters, are devices that convert a DC voltage from one level to another. They are widely used in applications where either a higher or a lower voltage needs to be generated from the available source. In this article, we will discuss the application field and working principle of one particular DC to DC converter, the RKZ-242005D.

Application Field

The RKZ-242005D is a wide input range Isolated DC DC converter designed to provide an isolated, regulated 24V output from an input source ranging from 6V to 36V. It can be used for a range of applications, including power supply for telecommunications equipment, mobile medical devices, instrumentation, embedded systems and automotive electronics. The high performance of the RKZ-242005D makes it suitable for applications that require precise voltage regulation, reliability and low operating temperatures.

Working Principle

The working principle of the RKZ-242005D DC DC converter is based on the flyback transformer topology. This topology is commonly used for the conversion of high voltage to low voltage. In the RKZ-242005D, the flyback transformer is used for isolating the dc to dc converter input and output, thus protecting the input from overload and overvoltage conditions.

The core component of the RKZ-242005D is the high frequency transistor switch, which is controlled by an internal oscillator. When current is applied to the primary side of the flyback transformer, it creates a magnetic field which induces a voltage in the secondary side of the transformer, and this voltage is regulated to the desired output level by the transistor switch. As the primary side of the flyback transformer is isolated from the output side, the secondary side voltage is isolated from the input voltage.

In order to regulate the output voltage, the internal oscillator is used to control the switching of the transistor switch, which is regulated by a feedback circuit. When the output voltage exceeds the desired level, the feedback circuit signals the oscillator to reduce the duty cycle of the transistor switch, thereby reducing the output voltage. On the other hand, if the output voltage is lower than the desired level, the feedback circuit signals the oscillator to increase the duty cycle of the transistor switch, thereby increasing the output voltage.

The RKZ-242005D DC DC converter is protected from overvoltage conditions by an integrated overvoltage protection circuit. This circuit monitors the output voltage and automatically disables the converter when the voltage exceeds the specified level, thereby protecting the circuit from damage.

Conclusion

The RKZ-242005D is a high performance DC DC converter designed to provide an isolated, regulated 24V output from an input source ranging from 6V to 36V. The core component of the converter is a flyback transformer, which is used for isolating the dc to dc converter input and output. The converter also has an integrated overvoltage protection circuit, which monitors the output voltage and automatically disables the converter if the voltage exceeds the specified level.

The wide input range and high performance of the RKZ-242005D make it suitable for a wide range of applications, including power supply for telecommunications equipment, mobile medical devices, instrumentation, embedded systems and automotive electronics. With its high efficiency, fast response time and reliable operation, the RKZ-242005D is an excellent choice for applications that require precise voltage regulation.
