DC to DC converters are widely used in modern electrical systems. These devices convert an input DC voltage to a different, often higher or lower, voltage level output. The VI-BVP-MX-F1 is a type of DC to DC converter featuring fixed output, onboard voltage adjustment and protection functions. This article will provide an overview of the VI-BVP-MX-F1 application field and working principle.

Applications of the VI-BVP-MX-F1

The VI-BVP-MX-F1 is a single-input, multiple output voltage polarity-reversing DC to DC converter unit specifically designed for applications such as military and aerospace, telecommunications, medical electronics, high-end automotive, and electric power systems. It offers an input voltage of 24V to 54V and high efficiency levels up to 90 percent. The maximum continuous output power is 300 watts while operating from an input voltage of 36V. It also offers multiple options for both isolated (up to 500V) and non-isolated outputs.

Built-in features such as input protection, soft start, and onboard current limiting, make this converter an ideal choice when it comes to obtaining high reliability for the applications it is intended for. Other features like remote On/Off, enable/disable modes, voltage sequencing, and polarity reverse protection further strengthen the user’s confidence in its overall performance.

Design of the VI-BVP-MX-F1

The basic design principles of the VI-BVP-MX-F1 include a buck-boost topology, a control pulse-width modulation (PWM) converter, and a current mode control technique. The internal circuitry is composed of a high frequency power switch, an active rectifier, a reverse-blocking diode, and an output filter. The switching frequency can be adjusted by using a resistor, allowing for flexibility in design.

Working Principle of the VI-BVP-MX-F1

And basic function of the converter is to convert a DC input voltage to another DC output voltage, isolating the two for safe operation. In the VI-BVP-MX-F1 design, when an AC input voltage is applied, the internal power switch turns “ON” and “OFF”, regulating the input current. This leads to an output voltage proportional to the input voltage. By regulating the switching frequency, the VI-BVP-MX-F1 is able of adjusting the output voltage and current.

The internal circuit design of the converter also permits the output voltage to be higher or lower than the input voltage by using the buck-boost topology. This technique is achieved by reversing the current direction in the windings. By reversing the current, the output voltage is elevated up to 24 or 36 volts depending on the model. In this system, the transformer core is designed to preserve the output voltage across the model range, and the converter uses a feedback compensation circuit to further improve the output voltage stability.

The VI-BVP-MX-F1 is also designed with safeguards to ensure reliable operation of the converter. These safeguards include fuse protection at the input power switch, as well as over-current, over-voltage, overtemperature, and short-circuit protection.

Conclusion

The VI-BVP-MX-F1 is a high-efficiency, high-reliability DC to DC converter specifically designed for military and aerospace, telecommunications, medical electronics, high-end automotive, and electric power systems. Its buck-boost topology, current mode control technique, and onboard safeguards make this model an ideal choice for reliable and efficient operation. Furthermore, its adjustable input voltage, multiple output options, and low-ripple designs enable its usage in a variety of applications.
