MGFS302405-R DC DC Converters\' Application Field and Working Principle

Introduction

MGFS302405-R DC DC Converters is the latest generation of high-efficiency, low-loss, high-current, wide-input, low-output voltage DC/DC converters from MG Electronics, which provide a reliable power supply solution suitable for various operation scenarios. The series has high-efficient synchronous rectification technology, ultra-wide input voltage range, as well as comprehensive protection functions, enabling the product to better meet the diverse needs of users. In this article, the application field and working principle of MGFS302405-R DC DC Converters will be detailed.

Application Field and Features

MGFS302405-R DC DC Converters is suitable for a wide range of scenarios, including industrial control, distributed power supply systems, radio and communication base stations, wind and solar power, medical instrumentation, automotive and aerospace, as well as 5G applications . Due to its numerous features, the system can satisfy various power supply needs in different operation scenarios.The features showcased by MGFS302405-R DC DC Converters include but are not limited to a high efficiency up to 98％ and a wide input voltage from 4.5 V to 36 V. Meanwhile, the system has a low weight, high current output of up to 30 A, comprehensive protection functions such as load short circuit protection and over voltage protection, as well as soft start technology that prevents sudden surges in input current during startup.

Working Principle

MGFS302405-R DC DC Converters belong to a kind of switching power supply, in which the direct current (DC) is converted to direct current (DC) with different voltage levels through isolation conversion. The product utilizes a two-stage topology that includes an input voltage conversion step (boost) and a DC-DC conversion step (buck).

Boost topology

The boost topology is the first stage of the two-step conversion process used in MGFS302405-R DC DC Converters. The working process is that the output voltage is higher than the input voltage. When the switch is turned on, current runs through the coil, and the current stored in the coil produces an EMF induction that increases with the amount of current stored.When the switch is off, the current stored in the coil is discharged, which means that the EMF induction in the coil is reduced. The load in the output is supplied by the capacitor connected in parallel with the coil, thereby providing a constant voltage output.

Buck topology

The buck topology is the second step in the conversion process of MGFS302405-R DC DC Converters. The operating process of the buck conversion is that the output voltage is less than the input voltage. The switch in this case works as an active transistor switch. When the switch is turned on, current will flow through the flyback diode into the coil, and when the switch is off, the current stored in the coil will discharge through the diode to the load.Meanwhile, the MGFS302405-R DC DC Converters utilizes synchronous rectification technology, which helps it to achieve high efficiency in buck conversion. It works in the same way as a normal diode except that both the switches and the diodes are integrated into one synchronous rectifier module. This makes the circuit more efficient as the switch can be used to regulate the current instead of just controlling the connection to ground.

Conclusion

MGFS302405-R DC DC Converters is a common choice of power supply device for applications like industrial control, communication base stations and distributed power systems. With features like high efficiency, wide input voltage range and low-weight, it can meet various needs in the operation scenarios. The working principle of the system is also described in the article, in which two conversion processes are involved: the boost and buck conversion. The synchronous rectification technology helps the buck conversion process to achieve a high efficiency.
