DC-DC converters are used to convert direct current (DC) from one voltage level to another, and the VE-26V-CW forms a specialized subset of this technology. This type of converter features better efficiency, protection circuits, and CAN communication capabilities. In this article, we will explore the application fields for this device and the working principles behind it.

VE-26V-CW Application Fields

The VE-26V-CW DC-DC converter is a wide input voltage range unit suitable for 48V input voltage applications. It has a peak efficiency of 95 percent and provides an output of 26V with up to 300W of output power. It has an isolated voltage of 400V and includes short circuit protection, over current and input under voltage protection. Its wide operating temperature range make it suitable for both industrial and automotive applications.

In industrial applications, the VE-26V-CW is used for powering industrial machinery and equipment such as robotic arms, conveyor belts, and test equipment. In automotive applications, the VE-26V-CW is used to power auxiliary loads such as infotainment systems, head-up displays, and advanced driver assistance systems (ADASs). Additionally, the VE-26V-CW can be used in both encased and portable power systems.

VE-26V-CW Working Principle

The VE-26V-CW is a self-oscillating DC-DC converter with synchronous rectification. It utilizes an isolated transformer to transfer power from the input to the output, and it also features a PFC controller to maintain voltage regulation. The PFC controller uses a hysteretic loop in order to compare the output voltage level and adjust the input current accordingly. Once the voltage has reached the desired level, a MOSFET is used to cut off the current supply and maintain the voltage.

Once the current is cut off, the primary and secondary side of the transformer are shunted to allow the output voltage to be transferred to the load. This process creates a fly-back effect where energy is fed back into the output which helps reduce the output ripple and noise.

In addition, the VE-26V-CW features synchronous rectification where a MOSFET is activated on the secondary side of the transformer to recirculate the current. By using this method, the efficiency is improved as less energy is lost when converting from alternated current to direct current.

Finally, the VE-26V-CW features CAN communication capabilities which allow for remote control over voltage regulation and monitoring of the converter performance. This is done through the Digital Multiplex Bus (DMB) CAN network, and it allows the converter to be monitored and regulated in real-time.

Conclusion

The VE-26V-CW is a wide-input voltage range DC-DC converter which is suitable for industrial and automotive applications. It has a peak efficiency of 95 percent, wide operating temperature range, CAN communication capabilities, and protection circuits. Its working principle includes a PFC controller for regulating the input current, a transformer to transfer the power from the input to the output, and synchronous rectification to increase the efficiency.
