DC DC Converters

VI-BW3-CW-F4 application field and working principle

DC DC converters are one type of power converter and an electronic device that converts direct current (DC) power from one of its source into another. It is the most primitive form of a power electronic converter, and there have been variations in the technology used for this purpose so far. There are different types of DC converters depending upon the source, its output power, its efficiency, its size, voltage rating and its operating temperature. However, it is widely used to create an interface between different power sources of various magnitude, namely in between AC and DC. As such, the significant advantage of DC DC converters over their AC equivalents is that it is capable of eliminating any possible loss caused while transmitting electricity across long distances.

The application field of the VI-BW3-CW-F4 type of DC DC converter is quite diverse and it can be used to convert an AC voltage to a DC voltage as per the requirement. It can also be used to reduce the current level of a DC voltage from a higher level to a lower one, and also to control the voltage level of a DC voltage from a higher level to a lower one. Moreover, the VI-BW3-CW-F4 type of DC DC converter is generally used in automotive batteries, computer peripherals, electric motor controllers, solar panels, and any other DC output applications.

The working principle of the VI-BW3-CW-F4 type of DC DC converter is based on the principle of controlling the output voltage level, in which the output voltage is reduced to a certain set point when the input voltage is higher than the required output. The output current of the converter can also be adjusted through an adjustment knob and this is done by varying the duty cycle of the switching device. This work is done by controlling the switching period of the MOSFET switch, which is responsible for controlling the output voltage and current. The MOSFET will stop conducting during the cut-off time and start conduction when appropriate conditions are met. The frequency of the switching circuit can be varied depending on the desired output.

In the VI-BW3-CW-F4 type of DC DC converter, there are two major types of power stages such as the reset inverter and the two-mode converter. In the reset inverter, it is necessary to employ a current limiting circuit to reduce the output current, while in the two-mode converter, it is necessary to reduce the output voltage to maintain the output current. Both the types of power stages operate on the same principle, however the two-mode converter can be enabled and disabled by switching the two switches so that it can control both the voltage and current.

DC DC converters are used for many applications where a single power source is necessary. It is ideal for use in most applications such as battery chargers, electric vehicles, sub-stations, mobile radio systems, LCD displays, and audio amplifiers. The VI-BW3-CW-F4 type of DC DC converter has been widely used because of its versatility, small size, and high efficiency.
