Series Connected Power Flow Control using Magnetic Energy Recovery Switch (MERS)

A new series connected power flow controller, called the magnetic energy recovery switch, has been investigated. It is characterized by four active switches and a dc-capacitor in each phase. The device is capable of injecting up to rated voltage within the current rating. It behaves similar to a controllable voltage source and a variable capacitor connected in series. A control algorithm has been developed in order to facilitate power flow control with these combined characteristics. Experimental results suggest the MERS to be a promising new power flow controller.
