DC to DC converters are one of the most popular types of electronic products in today\'s market. The VI-B1M-EX is one of the most common versions of this type of converter. The VI-B1M-EX is an isolated, isolated-output, high efficiency DC/DC converter, designed for applications such as industrial automation, telecommunications, military and aerospace, and medical electronics.

Application Field

The VI-B1M-EX is designed for use in a variety of applications. It is ideal for industrial control, such as motor speed controls, temperature and position controls, as well as in general-purpose communications, engine and power supply systems. It is also suitable for use in telecommunication systems, medical electronics, automotive, and aerospace applications, and for military and defense operations.

The VI-B1M-EX can also be used as the basis of a complete and isolated power supply system. It can regulate output power to a minimum of 0.48Volts and a maximum of 1000Volts. It provides a power efficiency of up to 96%.

This converter also offers a wide range of features and versatility, such as variable input voltages from 10 to 24V, output voltages from 0.48 to 1000V, and a wide choice of form factors. It also has an environmental rating of up to 25 Celsius.

Working Principle

The VI-B1M-EX is a switched-mode DC/DC converter which provides an isolated, high-efficiency conversion of an incoming DC input voltage into an output voltage of a lower or higher magnitude. This converter employs a topology in which the source and load sides are isolated.

The converter has two main stages. The power conversion stage consists of a voltage-driven transistor switch, an opto-coupled feedback circuit, and an energy storage device. This stage converts the input voltage into an oscillating signal, which is then converted into a rectangular pulse-width-modulated (PWM) switching waveform. This switching waveform is then applied to the output section which consists of a power switch and an inductor, which helps to minimize output voltage ripple.

The output voltage is regulated through a feedback loop that compares the output voltage to a reference voltage. If the output voltage exceeds the reference voltage, the opto-coupled feedback circuit will reduce the duty cycle of the converter to correct the output voltage. If the output voltage is too low, the circuit will increase the duty cycle. This ensures a smooth and reliable transfer of energy from the DC input power source to the output.

The VI-B1M-EX provides an isolated power solution with high efficiency and reliable operation. It is compatible with a wide range of input and output voltages, as well as a variety of form factors. Its low cost and high reliability make it an ideal choice for many applications.
