Conversion Methods to Explore for High Voltage DC-DC Converters

Posted by HV mtech on January 24th, 2020

Most appliances rely on DC power supply as they need a stable voltage. DC is direct current wherein the flow of current operates in one direction. The DC converters initiate the process of DC conversion effectively. Undoubtedly, DC voltage tends to generate continuous electricity, but after a certain period, it becomes weak. In such cases using an AC voltage coming from a generator can easily improve its strength while they travel via a transformer. 

AC is Alternating Current wherein there is a change in voltage instantly. AC supply often used for household needs is used as utility current for household needs. The utility current used in households is directly converted to DC with the help of circuitry comprising of a rectifier, transformer, rectifier as well as a filter. In the same manner, DC voltage is upgraded or downgraded to get the desired voltage, thus we need high voltage DC-DC Converters and the DC to DC conversion to work effectively to attain the desired voltage for which various conversion methods are used. 

Electronic Conversion: In the case of high voltage DC-DC converters present in electronic circuits, it utilizes switching technology. In switch mode, the high voltage DC-DC converters convert the level of DC by retaining that input energy for a temporary period. It gradually releases the energy at a separate voltage output. This switching conversion method is power saving as compared to linear voltage regulation, which throws out unwanted power in the form of heat. 

The higher efficiency of high voltage DC-DC converters in switched-mode decreases the heat drop and enhances the battery tolerance of any portable device. Most high voltage DC-DC converters are wisely designed for unidirectional movement. 

Magnetic Conversion: In such types of DC-DC converters, you will see the energy being saved and then released through a magnetic field in a specific transformer/inductor at a frequency that ranges between 300 kHz- 10 MHz generally, the DC-DC converter indicates switching converters as explained below. The circuits form an integral part of the power supply in the switched-mode power supply.  

Commonly Utilized Circuits: Non-Isolated Converters 

They are used when you need a slight change in the voltage. 

Step-Down (Buck) Converter: It is used to produce a lower voltage than the input. It is also known as a buck and the polarities remain the same as the input. 

Step-Up (Boost) Converter: It is utilized to produce a higher voltage than the input voltage and is termed as a boost. Here the polarities those remain similar to the input. 

Buck-Boost Converter: It can be used to increase or decrease the output voltage rather than the input voltage. If you are looking for high voltage dc power supply manufacturers to fulfill your DC conversion needs, visit their website www.hvmtech.com to learn more about their products.
