DC DC Converters

DC/DC converters are devices that are used to convert direct current from one voltage level to another. They can convert a higher voltage DC input to a lower voltage DC output, or a lower voltage DC input to a higher voltage DC output. DCDC converters are an essential component in many electronic systems, as they are often used to provide power supplies to components that require specific voltages.

VI-2NZ-EX-F2 is a device designed to provide DC voltage conversion from an input of 24 VDC to an output of 30 VDC. It offers 24 W continuous output power with high efficiency, small size, and low power consumption. The converter uses pulse width modulation (PWM) and pulse frequency modulation (PFM) techniques to ensure the desired output voltage is continuously met.

Application Field

The VI-2NZ-EX-F2 converter is used in various industrial, commercial, and residential applications. It is often used in robotics and automation systems, security and surveillance systems, power supplies, and other systems that require a regulated DC voltage. Additionally, it is used in electric vehicles, solar photovoltaic systems, mobile displays, monitoring systems, alarm panels, gaming consoles, and industrial machinery control systems.

Working Principle

The VI-2NZ-EX-F2 converter works by converting the input voltage to an intermediate AC voltage using a DC-to-DC buck converter. This AC voltage is rectified and filtered to form the output current that is regulated by the PWM and PFM techniques. The PWM technique is used to adjust the duty cycle, which controls the amount of energy that is delivered to the load, and the PFM technique is used to adjust the switching frequency to maintain a steady output voltage.

The pulse width modulation technique is used to adjust the average output voltage by changing the on/off ratio of the power switches. A higher duty cycle means that more current will flow through the load, thereby raising the output voltage. On the other hand, a lower duty cycle will reduce the output voltage. The PFM technique adjusts the frequency and the voltage, allowing for more efficient operation and improved power delivery.

The VI-2NZ-EX-F2 converter also features a wide input voltage range, from 18 to 30 VDC, and a wide temperature range of -40 to +85 °C. It is designed to meet stringent reliability and safety requirements, and has a high efficiency of up to 98%, making it ideal for applications that require high performance. Additionally, it includes a slew rate control function to provide smoother transitions between voltage levels, and protection against overload and short circuit.

In sum, the VI-2NZ-EX-F2 converter is a high-efficiency DC-to-DC converter designed to convert a 24 VDC input voltage to a 30 VDC output voltage. It offers a wide input range, low power consumption, and high efficiency, making it an ideal choice for a wide range of applications. With its PWM and PFM techniques, it ensures that the desired output voltage is maintained, and its wide temperature range and protection features make it a reliable and durable device for many industrial, commercial, and residential applications.
