Abstract: A series compensating electric power transmission system has an insulated type DC-DC converter that operates in the first through fourth quadrants, first and second DC voltage sources, and first and second power converters. In the converter, a first I/O positive terminal is connected to a first voltage source positive terminal. A first I/O negative terminal is connected to a first voltage source negative terminal. One of second I/O positive and negative terminals is connected to the first voltage source positive terminal. The other of the second I/O positive and negative terminals is connected to a second voltage source positive terminal. The first power converter converts power between the first I/O positive and negative terminals and first AC I/O terminals. The second power converter converts power between the second I/O positive and negative terminals and second AC I/O terminals. The second power converter is configured with a plurality of bidirectional switches.
