VI-2TK-EW

DC DC Converters

DC-DC converters provide energy conversion with the help of switches, transformers, capacitors and inductors. They’re primarily used for voltage regulation, voltage conversion and power distribution. They’re commonly used in a variety of applications, such as laptop computers, cell phones, photovoltaic systems and aerospace applications.

VI-2TK-EW Application Field

VI-2TK-EW is a topology of a multifuntional dc-dc converter, especially suitable for distributed power systems, in which the input power voltage is from 10V to 100V and has a wide output voltage range of 1V to 120V. DC-DC is a form of energy-conversion technology which has been widely used in many areas, especially in distributed power systems, including high-density point-of-load (POL) regulation.

VI-2TK-EW Working Principle

The VI-2TK-EW is a two-winding isolated boost converter whose output transformer is a constant-transconductance transformer. The two winding of this converter output are coupled via two transformers, with one end of each transformer connected to the output terminals. The secondary winding is connected to a set of switches, which are used to control the output voltage of the converter. The transformer is designed using a very high current-transfer ratio of up to 1000:1, which makes it suitable for high-density DC-DC conversion applications.

The working principle of the VI-2TK-EW is based on the transformer-switching principle. The transformer winding ratio, duty cycle of the switches and the capacitance of the output filter provide for the required control. The current through the primary winding is determined by the duty cycle of the switches, while the current through the secondary winding is determined by the transformer’s winding ratio. The output voltage is determined by the capacitance of the filter, as well as the switching duty cycle.

The primary benefits of the VI-2TK-EW are its high conversion efficiency, low noise level and wide input voltage range from 10V to 100V. It is also very suitable for distributed power systems, where high-density, low-noise and high-efficiency converters are required. The VI-2TK-EW is also capable of operating in cold-start conditions, making it a great choice for energy-critical applications.

Conclusion

The VI-2TK-EW is a topology of a multi-functional dc-dc converter, especially suitable for distributed power systems, in which the input power voltage is from 10V to 100V and has a wide output voltage range of 1V to 120V. It works with a wide input voltage range and its high current transfer ratio along with the other benefits make it an excellent choice for high-density, low-noise power systems.
