[Journal Submission] Do you know the difference between MOSFET and IGBT?

[Journal Submission] Do you know the difference between MOSFET and IGBT?

In recent years, many power supplies have adopted the "MOSFET method," which can reduce switching losses! We will provide suitable proposals to achieve high output and simplification.

This is an introduction to the "MOSFET method" in the circuit configuration of power supplies for xenon arc lamps. While the IGBT method has often been adopted as the switching element, it is considered difficult to achieve high frequency and, therefore, difficult to simplify. Our company is able to propose the "MOSFET method," which enables high output, simplification, and high-speed switching. It can generate large currents from low voltage inputs, and by simplifying the control circuit, reliability is improved. As a specialist in the field of power electronics, we are here to meet your needs. *For more details, please refer to the PDF materials (journal).

Case Study of Power Supply Adoption at High Temperatures: Fiber Optic Base Station Power Supply in Singapore

Case Study of Power Supply Adoption at High Temperatures: Fiber Optic Base Station Power Supply in Singapore

This is a case of a switching power supply adopted for fiber optic base stations (AG BOX) in Singapore, a world-class advanced IT country!

**Background** In the 2016 World Economic Forum, Singapore was recognized as "the most digitally advanced country in the world" with a score of 6.04 out of 7 on the NRI index. As part of its national strategy, Singapore is promoting a cutting-edge digital smart city project utilizing digital technologies. **Challenges** The fiber optic base stations (AG BOX) spread throughout the city are key to the project's success. However, the temperature inside the devices reached 65°C, which posed challenges for operational reliability with conventional power supplies from other companies. PULS's DIN rail switching power supply minimizes thermal loss and achieves high efficiency of 95%. It generates less heat, is compact, and has a fanless structure, making it maintenance-free, which led to its adoption for this project. For more details, please check the case study. **Contents** - Background of Singapore's smart city national plan - Explanation of AG Box - Aggregation Gateway Box - Power supply requirements under extreme high temperatures - Explanation of the DIMENSION Q series
