DC-DC Converters are one of the most widely used types of power converters used in a wide range of industries and applications. The VI-B34-EV is a type of DC-DC converter used for variable-input, variable-output applications. The VI-B34-EV is characterised by a compact and robust design, making it suitable for many of today’s demanding applications. This article will discuss the application field and working principle of the VI-B34-EV converter.

Applications

The VI-B34-EV converter is an ideal choice for applications that require a wide input voltage range and a wide output voltage range. These applications include, but are not limited to, power supplies for battery chargers, cell phone chargers, and tablet chargers, as well as applications that require a large amount of power such as motor drives, industrial robotics, laser cutters, and welder power. Furthermore, the VI-B34-EV is used in aircraft, solar cells, and LED lighting systems, due to its high efficiency and wide operating temperature range.

Working Principle

The VI-B34-EV consists of two main components: a high frequency current-mode PWM controller and an isolated flyback converter. The current-mode PWM controller provides high efficiency, low noise, and wide input voltage range, while the isolated flyback converter provides low cost, high power density, and high temperature operation. The VI-B34-EV also features soft-switching technology, which improves the efficiency of the converter and reduces the power losses.

The VI-B34-EV works by converting an AC input voltage into a DC output voltage using a transformer or magnetic isolator. This process is called power conversion. The input voltage is first rectified and smoothed, then it is processed through the PWM controller to produce a pulses that are amplified and applied to the flyback converter. The magnitude of the voltage pulses is then adjusted by the controller according to the desired output voltage. The flyback converter then converts these pulses to a DC output voltage and current.

The VI-B34-EV also provides a number of features that make it suitable for many applications. These features include over-temperature protection, over-voltage protection, input surge protection, output short-circuit protection, low standby power consumption, and output voltage adjustment. Furthermore, the VI-B34-EV is designed to be highly efficient, with its efficiency typically exceeding 93%.

In summary, the VI-B34-EV is a versatile power converter that can be used in a wide range of applications. It features a compact and robust design, a wide input voltage range, wide output voltage range, and high efficiency. Its features and robust design make it an ideal choice for applications requiring robust power solutions.
