A method as switches acting on current zero crossing point is proposed to control Matrix Converter. Bi directional Switch is acquired by two IGBT modules in definite formation. The real time control of these switches is realized by using single chip processor 80C196. Using this method, three phase current output tracking the three phase input signals defined is acquired. The frequency and amplitude of the output are also adjustable. To verify the feasibility of this control method, a sample device is made and got the results as expected. The whole device is simple and realizable. The control method has efficiency and the anti jamming performance is also enhanced.
