Application of Isolation and Protection Circuit for IGBT Gate Driver

Abstract

Objective of this paper is to discuss the state of art IGBT Gate driver design, which includes the different isolation techniques, compatibility with power device and advanced protections feature. As the industry pushes for higher power and higher switching frequencies power supplies, which use IGBTs for power conversion. Reference to this, IGBT gate drivers is being designed to their ultimate attainable efficiency, smallest footprint, size and weight. Design and development of the Gate driver relates to the expertise on the circuit design and power devices operating characteristics. The subject is vital in order to adopt the modern design for critical operation (i.e., Traction, Healthcare, Energy).
