MATLAB在电力电子技术中的应用 摘 要 关键词：MATLAB in power electronics application Abstract In the 1960s developed the power electronics. enabled the electrical energy to be possible to exchange and to control, has produced the modern each kind of highly effective energy conservation new power source and the alternating and direct speeder, was the industrial production, the transportation, the building work household automation has provided the modernized high technology and new technology, raised the production efficiency and peoples quality of life, caused the human society to produce the life to have the immense changes. The power electronics and the electric drive control system combined the electronic circuit electrical machinery dragging automatic control theory microcomputer principle and the application and so on multi-disciplinary knowledge, as a result of power electronics device own non-relatedness, for the power electronics circuit and systems analysis certain complexity and the difficulty, generally the commonly used waveform analysis and the partition linearization processing method studied the power electronics circuit. The modern computer simulation technology has provided the brand-new method for the power electronics circuit and systems analysis, may cause the complex power electronics circuit systems analysis and the design becomes is easier and is effective. The MATLAB is Corporation promotes by American Math Works uses in the numerical calculus and the graphic processing science computation software system is honored as “on the giant shoulders tool” the MATLAB early time mainly to use in control systems simulation, passed through expands unceasingly already became contains the correspondence electrical engineering optimization control and so on many domains the science computation software, might use in the power electronics circuit and the electric drive control systems simulation. This topic carries on the power electronics electron variable current ele
