DC-DC converters are widely used in power electronics, and the “VE－JNX－IX－S” stands for a voltage-variable interleaved buck-boost converter. This converter’s application fields and working principles are summarized below.

Field of Application: VE-JNX-IX-S converter is suitable for applications with mixed voltages and high power ratings. Its integration of voltage-mode control and interleaving features reduce the power losses associated with small-signal non-linear operation, making it well-suited for a wide range of power electronics applications. For example, it can be used as a low-voltage, high-current DC/DC converter, motor controller, or AC-to-DC converter.

Working Principle: VE-JNX-IX-S converters use both voltage-mode control and interleaving to increase power efficiency and reduce losses associated with small-signal non-linear operation. Voltage-mode control uses two fully interleaved stages, each with an inductive-capacitive output filter. This arrangement enables the converter to accurately control both the input and output voltages, while the interleaving ensures that the output voltage remains at a constant level. The output voltage can then be regulated by adjusting the duty cycle of each of the stages. The advantage of using voltage-mode control is that it requires a smaller overall circuit size compared to other control techniques.

In addition to voltage-mode control, VE-JNX-IX-S converters also have interleaving capabilities. This feature makes it possible to link multiple buck-boost converters together to form a larger system that can handle multiple AC or DC inputs. This creates a more efficient and cost-effective DC/DC power supply. Furthermore, the interleaving feature also enables the system to operate at higher frequencies, making it suitable for high-performance applications.

Finally, VE-JNX-IX-S converters include additional features that provide additional protection from overvoltage, overcurrent or short-circuits, making them highly reliable in mission-critical applications such as medical equipment, aircraft, or other sensitive areas.

In summary, VE-JNX-IX-S converter is suitable for applications with mixed voltages and high power ratings. Its combination of voltage-mode control and interleaving features provide advantages such as improved efficiencies, cost savings, and reliable operation in mission-critical applications. Also, it offers additional protection from overvoltage, overcurrent and short-circuits.
