一种用于低压直流电网应用的低成本固态断路器设计

A naturally cooled direct current (dc) solid-state circuit breaker (SSCB) is proposed for residential and commercial dc buildings applications, where cost, acoustic noise, and energy efficiency are critical concerns. By using the matrix connected low voltage mosfets to handle the main current, the proposed SSCB achieved 99.90%+ efficiency from 25% load and retained the ultrafast circuit breaking p...
