Bypass Switch for High Voltage DC Systems

Description:

Reference #: 01220

 

The University of South Carolina is offering licensing opportunities for a bypass switch for high voltage DC systems.

 

Background:

 

In many DC applications, switching converter modules are series-connected to achieve higher voltage operation. Typical examples are multiā€level converters. If a converter cell fails, it is desirable to be able to bypass it so that the rest of the converter can still operate, possibly at a reduced power level. Desirable features of a bypass switch are fast closing speed, high current capability, low conduction loss, and long lifetime (large number of possible closures without deterioration). 

 

Invention Description:

 

The invention relates to a bypass switch for high voltage DC systems designed to achieve higher voltage operation using a parallel combination of switches for the transmission of electric power.

 

Potential Applications:

 

The bypass switch allows the operation of a multi-level converter to continue even if a cell fails. Suitable for High-Voltage Direct Current (HVDC) applications and Direct Current (DC) power distribution systems.

 

Advantages and Benefits:

 

 Low cost, higher performance, faster switching speed, low conduction losses.
