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.
