Schematic diagram of superconducting magnetic energy storage (SMES) system. It stores energy in the form of a magnetic field generated by the flow of direct current (DC) through a superconducting coil which is cryogenically cooled. The stored energy is released back to the network by discharging the coil. Table 46.
A system that contains energy storing element(s), filtering element(s), high frequency switch(s) and produces DC voltage after applying DC input DC voltage is called a DC-DC converter. Isolated and non-isolated are mainly two types of DC-DC converter based on the presence of an electrical isolating element e.g. transformer [ 3 ].
