[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).
