STARTED WITH INDIRECT

While designing the matrix converter its easy to start with indirect matrix converter.In indirect matrix converter we have to design the rectifier part and the inverter pare separately.So as a start i designed a 3 level inverter with triangulation method for sector identification. In inverter made is a cascaded H bridge inverter and its a 3 level inverter.At the rectifier part uses the space vector approach so that to make the current a sinusoidal one.The rectifier part uses three separate rectifier for  cascaded H Bridge.By combining the rectifier part and inverter part we can made a indirect matrix converter.In indirect matrix converters unlike the inverter stages life limited bulky capacitors are not present which will increase the reliability and life time of matrix converter.

CASCADING H BRIDGE AND MATRIX CONVERTER TOPOLOGY....

matrix converter being a matured field I am thinking of designing a medium voltage high power matrix converter...Of them best one is cascading the existing multilevel topology along with matrix converter.....All multilevel topology except cascaded H bridge is can not be converted into multilevel easily..... i.e. in cascaded H bridge structure it can be easily converted into multilevel structure by designing small six switched prototype of matrix converter module....by cascading the small six stepped prototype of  Matrix converter we can easily make multilevel(3, 5 or 9 level) matrix converter.....So as a start I developed a two level SVPWM inverter and 3 level SVPWM inverter.....In designing the multilevel inverters using SVPWM we have to adopt different method for sector identification and identification of triangles in the sector...so in order to find the sector correctly I adopt triangulation method and converting the equations in alpha beta co-ordinates...Its a an easy method for sector identification....
