About
This invention utilizes current type auxiliary circuit to desaturate or saturate two phase legs of EE shape magnetic core to actively change the electromagnetic loop to form a reversed coupling inductor or a voltage injector. It uses forward type voltage injection circuit to inject voltage into the primary winding and reset the flux during saturation and desaturation mode of EE shape magnetic core. It also uses EMS or ECB and several DCPVIBBs in series to form a continuous DC voltage injection circuit. The controller is implemented to bring the current of main power loop down in a short time, and then ECB is turned off and fault current path can be completely shut down. A unique DCPVIBB-HCB without semiconductor devices in main power line is proposed, high efficiency, high power density, and fast response can be achieved simultaneously.
Key Benefits
1. High efficiency, high power density, and fast response can be achieved simultaneously. 2. Both source and current load side are limited during fault state. 3. Modular design makes it easier to scale the voltage and power to different stage.
Applications
1. Medium voltage DC transmission 2. DC power distribution 3. Micro-grid
