DC-DC converters refer to devices that provide a DC-to-DC conversion process, meaning power is transferred from a DC source to a DC load through an electrically isolated electronic circuit. DC-DC converters are primarily used in vehicle-based applications, such as in a battery system in a car, and have become increasingly important components in the automotive industry. The V110B8E150BL is an isolated DC-DC converter developed by Vicor Corporation that has specifically been designed for vehicle-based applications. This article will discuss the various application fields and working principles of the V110B8E150BL.

Application Field

The V110B8E150BL mainly offers an isolated, unregulated output voltage for applications including battery charging, DC/DC conversion, and protection, among many other applications. Vehicular applications are the main focus of this isolated DC-DC converter, mainly to provide charge to a 12V battery, and its output power capability is 290W. This DC-DC converter also features a wide input range of 9-36V, allowing it to be used in various systems and applications. The V110B8E150BL offers high efficiency for its operating temperature, with efficiency reaching up to 93% at an ambient temperature of 25°C. This DC-DC converter also features an operational temperature range of -40°C to +100°C.

Working Principle

The V110B8E150BL works on the transformer modelling principles, consisting of a high frequency power electronic switch, an output diode, an isolated magnetic circuit with windings, and a DC/DC converter\'s input/output capacitances. When voltage is applied to the primary side of the device, current passes through the electronic switch, which causes the transformer core to be magnetized. An alternating current is passed through the transformer windings of this DC-DC converter and induces a voltage on the secondary side. This converting technique allows for the output to be isolated from the input, making it safer and more reliable. The voltage fed back to the primary side will help modulate the output voltage, allowing for higher precision.

Conclusion

The V110B8E150BL DC-DC converter is specifically designed for vehicular applications, offering up to 290W of output power and efficiency up to 93%. The main principle behind this isolated converter is transformer modelling, featuring a high-frequency power electronic switch, a diode, and input/output capacitances. This DC-DC converter can be used in various systems with its wide input voltage range and features high efficiency for its operating temperature. Therefore, the V110B8E150BL is a perfect choice for vehicle-based applications needing an isolated DC-DC conversion.
