DC DC Converters -- VE-BNV-EW Application Field and Working Principle

DC-DC converters perform the essential function of converting DC electricity from one form to another. The common type of DC-DC converters are the Voltage-Boost type, the Buck-Boost type, and the EW type. This article will discuss the Voltage-Boost type and the Buck-Boost type converters, and the characteristics and operation of these two types.The Voltage-Boost (or VE-BNV) type DC-DC converter is used for a wide range of applications, including battery charging, DC motor control, and in systems where higher voltage is required for operation. It provides regulated output voltage, regardless of the input and load conditions. The working principle of an VE-BNV converter is based on the use of a voltage multiplying transformer. That is, the transformer increases the voltage by a certain factor, and the device is used to both step up and step down the voltage. To obtain a regulated output voltage, the direction and the rate of the input current must be adjusted with respect to the rate of the output voltage. In this kind of converter, a control circuit consisting of integrated electronic switches, and a series of magnets, enables this modulation. When the input and output voltages are unbalanced, the magnets interact with the switches , causing the current to be re-circulated in the transformer. Moreover, this type of converter eliminates the need for a boosting inductor, thus simplifying the device and reducing the parts count. The Buck-Boost type DC-DC converter is similar to the Voltage-Boost type in that it adjusts the input current with respect to the rate of the output voltage. However, the Buck-Boost type converter works in two directions. That is, it works both in the "boost" direction, from a lower voltage to a higher voltage, as well as in the "buck" direction, from a higher voltage to a lower voltage. As such, it can be used in a wider range of applications, such as for computer power supplies and motor drives. The working principle of the Buck-Boost type converter is based on the use of a high-frequency booster-inverter, which converts the input AC voltage to a higher or lower AC voltage. This is done by adjusting the transistors\' firing angle, and hence the frequency of the AC voltage, in order to step up or step down the voltage. Furthermore, the control circuit and magnet are combined in a single device, which eliminates the need for a boosting inductor. In summary, the Voltage-Boost type and the Buck-Boost type DC-DC converters are devices that are used to convert DC electricity from one form to another. Both use voltage multiplying transformers, and adjust the input current according to the rate of the output voltage. The Voltage-Boost type is used mainly for applications where a higher voltage is needed, while the Buck-Boost type can be used in a wider range of applications, due to its two-way action. Moreover, the control circuits and magnets used in these converters simplify the devices, and reduce the parts count.
