This Seven Level Diode Clamped Multi Level Inverter seminar topic is mainly explains you about the multi level inverters by using seven diodes clamping circuitry. This topic mainly uses the concepts of diode clamped inverter, multi level inverter, PWM (pulse width modulation) switching techniques. When photovoltaic system connected to a two level inverter then there may be mismatching or shades may occur, so that there may be reduction in power, so to avoid this problem of power reduction there we use multi level inverter instead of using two level inverter, so here high voltages are involved by using thyristors we can control the voltages and currents, thyristor can control the Mega Watts of power generated. Here pulse width modulation scheme is used; pulse width modulation scheme is used in five level and seven level diode clamped multi level inverters (DCMLI).

This DCMLI technique is implemented using the MATLAB programming and the total harmonic distortion is compared with two levels and seven levels, in this seminar topic explains you about the diode clamped multi level inverter, PWM method for the seven level DCMLI (seven level inverter model), observation of the five level and seven level DCMLI, and total harmonic distortion comparison. So for high power applications seven level diode clamper with multi level inverter is used.
