Design of an Integrated Self-Switching Mode Device for Power Converters

In this paper, we present a design procedure for the integration of a new specific function based on the association of a ZVS mode thyristor and a circuit breaker dedicated to self-switching mode power converters. This function, based on the functional integration concept, monolithically associates protection, self-drive and power switch functions. This function uses an original switching mode of operation. After presenting the characteristics of the function and the function specifications, we focus on the different design steps: function optimization and cells sizing using 2D electrical and technological simulations, and mask design.
