DC DC Converters

VE-JWJ-EY-B1 application field and working principle

DC-DC converters are electronic devices that converts a DC input voltage into one or moreDC output voltages, either providing an isolated voltage conversion or an AC to DC conversion. DC-DC converters are used to optimize or adapt voltage levels for electronics applications requiring lower or higher voltages than the original source. Application fields of DC-DC converters include solar energy systems, automobiles, consumer electronics, telecommunications, aerospace, medical equipment and instrumentation systems.

There are two main types of DC-DC converters: isolated and non-isolated. Isolated DC-DC converters use a transformer to isolate the input and output circuits, while non-isolated converters don’t use a transformer, relying on an electrical connection, like a capacitor or inductor, to provide the electrical insulation. Isolated DC-DC converters are usually higher performance than non-isolated converters, due to the ability of the transformer to reduce noise and voltage ripple.

VE-JWJ-EY-B1 DC/DC converters

The VE-JWJ-EY-B1 DC-DC converter is an isolated converter designed for industrial applications that require high input to output isolation voltage. It supports input voltage ranging from 30 to 180 V, and output voltage ranging from 3.3 to 15V. The conversion efficiency of the converter is typically 90%. It also has a wide operating temperature range, from -40 to +85 degrees Celsius, making it suitable for use in harsh environments. It includes a built-in EMI filter, which ensures the output voltage is free of noise and distortion.

The VE-JWJ-EY-B1 uses a buck-boost principle to convert the input voltage to its output voltage. It works by first converting the input voltage to a higher voltage and then using a buck-boost circuit to regulate the output voltage to the desired level. The buck-boost circuit allows the converter to maintain a constant output voltage, regardless of the input voltage.

The VE-JWJ-EY-B1 is ideal for applications that require a high degree of input to output isolation, such as automotive, battery operated devices, industrial and medical applications. With its wide temperature range and high conversion efficiency, the converter provides reliable performance in harsh environments.
