DC-DC converters are widely used in a variety of applications against both AC and DC power systems. Some of these applications may include telecom systems, computers, and space systems. The VI-21V-CW is a dc-dc converter commonly used to convert voltage from one level to another for power conditioning purposes. In order to understand the VI-21V-CW, it’s important to understand the operating principles of dc-dc converters and the associated application fields.

Operating Principles of DC-DC Converter

The most basic dc-dc converter is the "boost" converter. In this type of converter, an input voltage is fed through an inductor and a diode to a capacitive load and then back to the input voltage. By controlling the duty cycle of the switch, the amount of voltage that is delivered to the load can be controlled. Other types of converters include the "buck", "standby" and "synchronous" types.

A "buck-boost" converter uses a combination of a buck and boost converter to effectively step up or down an input voltage. By controlling the duty cycle of the switch, the amount of voltage that is delivered to the load can be controlled. This type of converter is often used for applications where an input voltage of one level is converted to a voltage of another level.

A "variac" is another type of dc-dc converter. This type of converter uses an inductor to adjust the amount of voltage delivered to the load. By adjusting the inductance of the inductor, the amount of voltage delivered to the load can be adjusted.

VI-21V-CW Application Field and Working Principle

The VI-21V-CW is a multi-purpose DC-DC converter designed to provide power conditioning services under a variety of conditions. This type of DC-DC converter is suitable for converting input voltage from 24 Volts to output voltage up to 21 Volts with up to 28 Watts of maximum power.

The VI-21V-CW is a "buck-boost" DC-DC converter that achieves excellent efficiency of up to 90% with a frequency of up to 40kHz. This converter uses a high-speed low-drop-out control scheme which means that a certain level of input voltage is maintained even where the source voltage fluctuates. This power conditioning controller is also equipped with a protection circuit to protect the system from over voltage, under voltage, overload, and over-temperature.

In applications where the VI-21V-CW is used, the converter is designed specifically for reliable, steady operation in environments with high levels of electromagnetic interference (EMI). This converter provides high levels of noise immunity which is essential for system stability in highly EMI environments. In addition, the converter also provides control and monitoring functions to allow for efficient adaptation to changing environmental conditions.

The VI-21V-CW design features an open frame configuration, allowing easy access to the power supply components, and the converter can be easily modified with additional components or custom-built circuits. This makes the VI-21V-CW a very versatile choice for a wide range of applications.

Overall, the VI-21V-CW is a versatile, reliable and efficient DC-DC converter that provides power conditioning services under a variety of conditions. It has a high level of EMI immunity and can be customized with additional components or custom-built circuits. In addition, it features an open frame configuration that allows for quick and easy access to the converter components. This makes it ideal for use in a variety of DC-DC applications.
