DC-DC Converters

VI-B3W-MV Application Field and Working Principle

DC-DC converters are electronic power modules for converting a constant voltage DC power supply into a variable voltage DC power supply. They are used as part of the electrical circuitry in power supplies, chargers, motors, etc. The VI-B3W-MV is a DC-DC converter developed by Vicor that can provide a variable voltage, up to 300V, DC power from a 12V or 24V input voltage. It is primarily used in automotive systems, such as electric vehicles. In this article, we will go over the application field and working principle of the VI-B3W-MV DC-DC converter.

Application Field

The VI-B3W-MV DC-DC converter is designed for automotive applications. It has a wide input voltage range of 6V to 24V, making it suitable for 12V or 24V vehicle power systems. It also has a wide output voltage range of up to 300V, making it ideal for in-car charging, electric vehicle systems, and other high voltage applications. Due to its high efficiency, the VI-B3W-MV is well-suited for automotive applications where space is at a premium, as it can save significant space due to its small size.

Working Principle

The VI-B3W-MV DC-DC converter is based on a buck-converter topology. In a buck converter, the input voltage is first transformed into an alternating current (AC) voltage by an integrated transformer. The AC voltage then passes through a bridge rectifier to convert it into DC voltage. The DC voltage is then transformed into a variable voltage using MOSFET switching technology. The output voltage can be adjusted by changing the duty cycle of the MOSFET switching components. The output voltage and current are monitored and regulated using a current-mode control algorithm. The VI-B3W-MV also features a burst mode operation, which enables the device to operate in an energy saving mode, even at low input voltages.

Conclusion

The VI-B3W-MV DC-DC converter is a space-saving, high-efficiency DC-DC module for automotive applications. It is based on a buck-converter topology, with an integrated transformer and bridge rectifier to convert the input voltage to a variable output voltage. Its wide input and output voltage ranges enable it to be used in a variety of applications, such as electric vehicle systems and in-car charging. The VI-B3W-MV also features an energy-saving burst mode operation, allowing it to reduce power consumption even at low input voltages.
