DC-DC converters are objects that convert a direct current (DC) from one voltage to another. DC-DC converters are used in automotive and aerospace applications, as well as for portable devices such as laptop computers, to keep the voltage relatively constant. DC-DC converters are also widely used in LED lighting, solar, wind, communication, and power quality applications. Among the widely used DC-DC converters is the RKZ-2412S/H.

RKZ-2412S/H Application Field

The RKZ-2412S/H DC-DC converter is specifically designed for high power applications, ranging from 150W to 600W in input power. It is designed to fit in existing COTS enclosures for quick integration into existing designs. It is also designed to meet MIL-STD-704D transient voltage requirements and EMI/RFI standards. It provides an adjustable output voltage from 0.55V to 28V, and is capable of withstanding up to 15,000V DC shock.

This series of converter is suitable for a variety of applications; such as control systems, test stands, and other related applications requiring an input power source for powering a variety of devices. It is also a great choice for military and commercial aerospace applications, test equipment, high-end medical device applications, and other applications requiring a reliable and robust power source solution.

RKZ-2412S/H Working Principle

The RKZ-2412S/H DC-DC converter uses a synchronous rectifier circuit with a single primary winding and an auxiliary winding to generate a regulated DC output voltage. The primary winding is connected to the AC input voltage, which is rectified and filtered to provide an unregulated direct current (DC). The auxiliary winding is connected in series with the primary winding, and provides a regulated DC output voltage.

The DC voltage from the power transistors is first filtered and then sent through an inductor-capacitor (LC) filter. The LC filter removes any RF noise, spikes, or transients that might be present on the power lines. The regulation of the output DC voltage is achieved by adjusting the voltage across the auxiliary winding. The output voltage is regulated by the synchronous rectifier circuit, which ensures the output voltage permits for fast and stable load regulation.

In addition to providing a clean, regulated output, the RKZ-2412S/H features power factor correction (PFC) and soft start capabilities. The PFC circuitry helps to reduce input power line current harmonics, which reduces stress on the AC power system. The soft start circuitry helps to eliminate in-rush current that can cause stress to other components connected to the DC-DC converter.

Conclusion

The RKZ-2412S/H DC-DC converter is a reliable, high-power device that is designed for use in challenging applications. Its adjustable output voltage and power factor correction capabilities make it suitable for a variety of demanding applications that require reliable power sourcing. Its MIL-STD-704D-compatible EMI/RFI filter and shock tolerance further make the RKZ-2412S/H the go-to choice for high-end power sourcing needs.
