Power inverter - Wikipedia power inverter, or inverter, is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of "converters" which were originally large electromechanical devices converting AC to DC.
Voltage Sensor: Working Principle, Types & Circuit Diagram ... Is A Voltage Sensor?
R&D and application of voltage sourced converter based ... a new generation of direct current (DC) transmission technology, voltage sourced converter (VSC) based high voltage direct current (HVDC) has been widely developed and applied all over the world. China has also carried out a deep technical research and engineering application in this area, and at present, it has been stepped into a fast growing period.
Electrical Substation Design, Modification & Construction Switchgear Substations (GIS ). Gas-Insulated Switchgear Substation units can be up to five times smaller than Air-Insulated Switchgear Substation units, which often times equates to considerable cost savings and requires smaller, less intrusive housing structures.

Figure 10: 145 kV dead tank based compact switchgear Circuit breakers with combined functions will also contribute to further improvements of the reliability of the total substation. A typical example is the high voltage circuit breaker with a dis-connector function.
HVDC converter station - Wikipedia HVDC converter station (or simply converter station) is a specialised type of substation which forms the terminal equipment for a high-voltage direct current (HVDC) transmission line. It converts direct current to alternating current or the reverse. In addition to the converter, the station usually contains: . three-phase alternating current switch gear
Converter stations - Manitoba Hydro stations. A lot of Manitoba's electricity is produced by our northern hydroelectric generating stations on the Nelson River. The electricity travels long distances on bipole transmission lines to southern Manitoba as high-voltage direct current.. It is more efficient and economical to transmit electricity as high-voltage direct current.
