New Energy and Power Conversion: System Integration, Technique Fusion and Application Prospect

This paper discusses some problems on new energy and its power conversion. These problems will be important for the applications of new energy power systems. The main topics of the paper will be focused on the power conversion, system integration and technique fusion. First the paper outlines some new electrical production methods with new energies such as fan generators, solar cells and fuel cells. And the core roles of power converters in the new energy electrical source systems will be presented as the common problem and key techniques to be attention. For this reason now some converters, particularly DC-DC converters and DC-AC inverters, widely used to construct an integrated power system with new energy electrical systems. Furthermore the paper presents the idea of technique fusion, in which the techniques of modern power supply, power conversion, control methods, security protection and intelligent management will be combined into a synthetical method to solve the coming problems. At last the paper prospects the applications including hybrid power supply methods by different energies, distributed electricity systems and pocket power systems for communication, electrical vehicles and ocean monitoring in the future.
