A Modular Switching Position with Voltage-Balancing and Self-Powering for Series Device Connection

Medium-voltage converters, especially those making use of SiC devices, require high common-mode voltage immunity and resilience against associated high dv/dt across multiple isolation barriers. A truly modular and common-mode immune switching position could be beneficial for these applications. The design of a modular switching position is presented here for a series connection of power semiconduc...
