DC DC Converters

DC DC converters are electronic tools used to convert a direct current (DC) power source to a different voltage, current, and/or power format. They are primarily used in applications where the input power source produced from a direct current (DC) source needs to be converted to a different voltage, current, and/or power output. The main types of DC DC converter are:

• Linear Regulated DC to DC Converters
• Switching Regulated DC to DC Converters
• DC to AC Converters
• DC to DC Boost Converters

The VI-2WP-CV is a type of DC/DC converter developed by International Rectifier, and is an advanced, high-performance Buck Voltage Mode (BVM) converter. BVM technology is used to achieve excellent output regulation, low output ripple, and high efficiency. This converter is the industry standard in high efficiency Power Factor Correction, with an input range of 2:1 to 4:1, with an adjustable output up to 400V.

VI-2WP-CV Application Field

The VI-2WP-CV is designed for a wide range of applications, including low power consumer electronics, automotive, LED lighting, LED systems, chemical process control, and industrial process control. It is suitable for a variety of uses, including high switching frequency, low noise, and advanced output regulation.

VI-2WP-CV Working Principle

The VI-2WP-CV uses a two-stage voltage mode power conversion topology. This topology utilizes an input voltage switch, a buck converter, and an output voltage switch. The input voltage switch enables the use of low voltage taps, so the buck converter can operate at higher switching frequencies. The buck converter is a single switch topology, which provides isolation, minimum output ripple, and low maximum supply current.

The output voltage switch is a dual-switch topology that provides higher efficiency and the ability to adjust the output voltage range. This Voltage Range Adjust (VRA) feature makes it possible to meet the most stringent voltage tolerances. The VI-2WP-CV also provides a low-noise operation and is able to drive higher power loads.

Conclusion

The VI-2WP-CV is an advanced DC/DC converter that is suitable for a variety of applications. It is designed to provide high efficiency, low noise, and excellent output regulation. This converter is the industry standard in high efficiency Power Factor Correction, with an input range of 2:1 to 4:1, with an adjustable output up to 400V.
