Over the past few years, high DC DC converters (which are also known as linear converter or switching regulator) have been drawn attention because of their wide-ranging not only in the renewable energy sector but also in many other applications of various industries. To acquire a high voltage gain in industrial applications, a high linear converter is proposed in this article.

The key features of the linear converter are:

• A minimal number of major components
• A minimum size of boost stage that ensures its low cost
• High voltage output with lower voltage stress

Essential for industry purpose:

The simple characteristic of industrial DC DC converter is that it is easy-to-use devices that can handle input voltages. Industrial applications are inexhaustible. However, the poor effectiveness of the power adaptation system is the main obstruction to their development. The output voltage relatively fluctuates and low. Hence, the high-efficiency and high-gain switching regulator is essential to boost up the output with the required input voltage for different AC and DC loads.

In addition, to enhance the energy supply accessibility of the poor battery converter can be utilized as a backup. The linear converters having a higher efficiency along with a high-gain are suitable during the battery discharge period. Therefore, a cost-effective and high-gain switching regulator with the high-efficiency property is essential in industrial as well as many other applications.

Application of conventional strategies:

Complexities arise in the case of extremely high power, such as switch turn-off period. Voltage stress in the active devices is equal to the converter’s output voltage and it gets increased with high voltage applications. This escalates the price of converter devices. Moreover, because of the high current of the power devices are high during high-voltage gain operation.

To reduce this loss in conventional linear converters, many techniques have been proposed. Converters designed based on conventional strategies need to be operated. Even the engineers are designing AC DC power converters to simplify the task of the power supply and it provides reliable performance like the switching regulator. It lowers the stresses of active devices.

Lower weight, size and the price of the modern converter:

A good number of switching regulators have been investigated until now to attain high voltage ratio by using a high-frequency transformer. Transformer energy can be achieved by the utilization of converters which boosts up the application. Although the linear converter propped to offer higher efficiency at lower power, the utilization of this converter causes a high voltage of high rating devices.

A switching regulator, which is non-isolated converter, is applicable for low power appliances. This converter provides low input current, low active device voltage stress, and the high voltage ratio. Moreover, if the converter reduces the weight, size, and overall complexities of the converter, it will automatically lower the price.

The function of the switched capacitor:

The switching regulator is designed by the switched capacitors which can operate at higher temperatures. The voltage ratio can also be increased to a high value by utilizing the linear converter. The capacitor of this converter is considered as some other voltage source to attain a high voltage gain. This converter offers a high gain in high voltage systems. The beneficial features of industrial DC DC converter are the reduced capacitance and the lower capacitor. However, the requirements of more elements increase the overall converter complexity.

Traditional vs. modern linear converter:

The switching regulator offers high gain and offers high voltage conversion ratio with a simple structure. In addition, the control techniques used in the traditional linear converter can be simply applied to various applications. The benefits of the widely used traditional converter work well in high voltage and where you see a low capacitor. Today’s converters are cost-effective and are reducing their size day by day. The switching regulator provides high gain without a high-frequency transformer.

Bottom Line:

The linear converters are broadly considered as a significant part of most of the renewable energy systems and many other applications. The voltage stress on different devices is different. The converter offers high voltage stress. The number of major components uses in the model is really effective for the applications.
