VI-B0X-IX-S

VI-B0X-IX-S DC DC Converters Application Field and Working Principle

A DC-DC converter is an electrical device that converts a source of direct current (DC) power to a different target DC voltage. It can vary the terminal voltage, current or power as well as provide electrical isolation and protection. DC-DC converters are used in a wide variety of applications, from battery systems to automotive, aviation and industrial applications.

The VI-B0X-IX-S is an advanced high power density DC-DC converter, specifically designed for automotive applications. It offers an impressive power capacity of 28 volts / 50 Amps, and can operate at temperatures ranging from -40°C to +85°C.

It is designed with a high efficiency, high power factor, and is also capable of fast transient response. This makes it ideal for applications where quick response and accuracy of motion control is required, such as engine and transmission control, fuel injection systems, engine diagnostics, automotive lighting, climate control systems and electric vehicle control. The VI-B0X-IX-S is also designed for FC, full cut-off, as well as PWM, pulse width modulation, and adjustable current limit.

Working Principle

The VI-B0X-IX-S operates according to a flyback topology. This type of converter is designed to store magnetic energy during switching events, and then release it to the output. In this way, a certain amount of energy is buffered and the goal of fast transient response is achieved. It also allows the use of a transformer with a lower frequency operation than a Buck converter for the same output power.
