Loss and Thermal Modeling of Metal Oxide Varistors (MOV) Under Standard Current Surge Mission Profile [PDF]

open access: yes2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019
Because of their crucial role in protecting power electronic equipment against over-voltages and transients, metal oxide varistors (MOV) represent a key component of the electrical system. Although improper heat dissipation and internal temperature rises can lead to a significant decrease in performance or even to a wear-out failure of the MOV, there ...

A novel embedded voltage‐clamped circuit for multilevel modular converters submodule to suppress very fast transient overvoltage

open access: yesHigh Voltage
The submodule in multilevel modular converters experiences a very fast transient overvoltage (VFTO) during switch operation of gas‐insulated switchgear, which also results in overvoltage on power devices, such as thyristors and insulated gate bipolar ...
