Power converter and method of operation with current crowbar

摘要

A power converter (100) includes a first phase leg (102) including a first di/dt reactor (120) and a first control section, the first di/dt reactor and the first control section being coupled between an active line and a neutral line. The power converter also includes a first current crowbar (124) coupled between the active line and the neutral and a controller coupled to the first di/dt reactor, the control section and the first current crowbar and configured to activate the current crowbar based on a voltage across the first di/dt reactor.
