The power electronics and the electric drive control system bined the electronic circuit electrical machinery dragging automatic control theory microputer principle and the application and so on multidisciplinary knowledge, as a result of power electronics device own nonrelatedness, for the power electronics circuit and system39。s analysis certain plexity and the difficulty, generally the monly used waveform analysis and the partition linearization processing method studied the power electronics circuit. The modern puter simulation technology has provided the brandnew method for the power electronics circuit and system39。s analysis, may cause the plex power electronics circuit system39。s analysis and the design bees is easier and is effective. The MATLAB is Corporation promotes by American Math Works uses in the numerical calculus and the graphic processing science putation software system is honored as “on the giant shoulder39。s tool” the MATLAB early time mainly to use in control system39。s simulation, 3 passed through expands unceasingly already became contains the correspondence electrical engineering optimization control and so on many domains the science putation software, might use in the power electronics circuit and the electric drive control system39。s simulation. This topic carries on the power electronics electron variable current electric circuit39。s simulation in the MATLAB foundation, studies and pares each kind of power electronics electron variable current electric circuit using the modern emulation technique.
