A MOSFET based solid-state power controller for aero DC networks

Research output: Contribution to conference › Paper › peer-review

Abstract

This paper details the design, construction, and testing of a MOSFET based solid-state power controller rated at 270V, 200A, equivalent to 54kW, with an overload capability of 400A. The power switch is a parallel array of 21 fractionally rated Si MOSFET devices which current share to achieve the overall rating while minimising on-state losses. A transient voltage suppressor is used to dissipate inductive energy and protect the power switching devices. Results analysing on-state losses, thermal performance, inrush current limiting, inductive load breaking, and over-current response times are discussed.
