Introduction

DC-DC converters are power electronics components that convert one DC voltage into another higher or lower DC voltage. This conversion is usually done with the help of modern semiconductors such as transistors, diodes, and other components. In this article, we will focus on the VE-260-MW-S application field and working principle.

VE-260-MW-S

VE-260-MW-S is a new DC/DC converter that belongs to the sophisticated and high performance VE-260 series. It is a switch-mode, continuous-conduction, 1-Input, 2-Outputs, boost DC-DC converter and belongs to the high voltage DC/DC converter family.

Features

The VE-260-MW-S DC/DC converter features a wide operating input voltage range from 6V to 40V, and a typical efficiency of 93%. Besides, the maximum output current is 8A, and the output voltage is adjustable from 2.5V to 45V. It also supports working ambient temperatures from -40℃ to +85℃. Moreover, the additional features of this converter are short-circuit protection, over-current protection, over-temperature protection with thermal-shutdown capability. It is also qualified for the automotive market according to ISO7637, and it has a working lifetime of over 200K hours @ 25℃, full-load, and 40V input voltage.

Applications

The VE-260-MW-S is designed for a wide range of applications, such as automotive applications, professional industrial apparatus and telecom equipment. Due to its high efficiency, small size, and high power conversion rates over a wide range of temperatures, it is also suitable for UPS (Uninterruptable Power Supply) systems and solar power systems.

Working Principle

The VE-260-MW-S utilizes a switch mode of operation and it contains a high-frequency switching circuit and uses an inductance-capacitance type of filter circuit. The basic structure is two loops, with the two parallel loops connected to a controlling electronic switch. When the electric switch is turned on, the power from the input terminal will be converted into an inductive energy stored in the choke coil, then, when the switch is turned off the energy stored is released in the form of electric current which forms the output voltage. In addition, when the electric switch is turned off, a diode is turned on, allowing the current to flow through the stored capacitance, and it will immediately maintain the input voltage and output voltage balance. The combination of the two loops works together to get the desired output voltage and current, which is regulated by the controller. The controller is responsible for controlling the switching frequency, regulates the on-time or off-time of switching, and provides the necessary protections for the converter from harmful input overvoltages or output short-circuits.

Conclusion

In conclusion, the VE-260-MW-S converter is designed to offer: (1) high-power efficiency, (2) small size, (3) high-power conversion rates over a wide temperature range, (4) short-circuit and over-temperature protections, (5) long working lifetime, and (6) high voltage DC/DC conversion. It is suitable for automotive, industrial, and telecom applications, as well as solar power systems and UPS systems. The working principle of this converter is based on switch mode operation and utilizes the combination of two loops, with the two parallel loops connected to a controlling electronic switch.
