DC DC Converters

A DC DC converter is a type of power conversion device which converts a Direct Current (DC) input to a different DC voltage or current output. In general, they are used to provide a regulated output voltage from either an AC source or a DC source and can be categorized based on the topology used. V72A5M300B is one of these DC DC converters, and its application field and working principle will be discussed in this article.

Application Field

The V72A5M300B is an optimal choice for powering distributed systems and industrial applications due to its wide input voltage range (88 to 528 V DC) and high efficiency (up to 96%). It is suitable for operating in Harsh Environments (Industrial & Military) as it qualified to MIL-STD-810F (521.5), MIL-STD-1275 and MIL-STD-461E for EMI/EMC standards.

Additionally, V72A5M300B is an ideal solution for applications requiring multiple voltage outputs such as Uninterruptable Power Supply (UPS), Variable Frequency Drive (VFD), HVAC systems, aerospace, avionics and military. Moreover, it can be used in safety critical and critical-systems due to its EN60950-1 compliance.

Working Principle

The V72A5M300B utilizes a self-regulated fully-bridge controller along with an external field-effect transistor (FET) as its main components to convert input voltage and current into a desired output voltage and current. It performs this by using an adaptive peak current limiting modulated hysteretic control method to regulate the voltage and current outputs.

The self-regulated fully-bridge controller monitors and controls the output voltage based on the input voltage and output current. Using a reference voltage, this controller adjusts the duty cycle of the drive signal to the FET to maintain a constant voltage output. For applications which require constant current outputs, the controller adjusts the duty cycle of the drive signal to maintain the desired current.

For applications requiring multiple output voltages, the V72A5M300B can be used in a parallel configuration with one or more additional converters. In this configuration, the self-regulated fully bridge controller is connected in series with the additional converter and uses a second reference voltage to adjust the duty cycle and regulate the output voltages.

Conclusion

The V72A5M300B is one of the most capable DC DC converters for providing regulated output voltage and current in harsh environments. Its wide input voltage range and high efficiency make it an ideal choice for powering distributed systems and Industrial applications. It supports both voltage and current regulation and can easily be used in a parallel configuration, making it highly versatile in terms of applications.
