Abstract -High power equipment are utilized in each power transmission and plentiful industrial applications. it’s Mickey Mouse to use typical power convertor, thanks to its power rating. A construction power convertor structure was introduced to cut back the disadvantage in typical power convertor. To get a top quality output voltage with minimum quantity of ripple content, they need high switch frequency along side advance pulse dimension modulation ways. This paper presents a completely unique modulation technique for imbalance diode clamped multi-level electrical converter to provide a curving output. the most objective of the planned modulation theme is that the reduction of switch losses with smart harmonic performance. The principle of 3 Reference Modulations seven level curving Pulse dimension Modulation (TRM – SPWM) is analyzed well. This paper is especially converges on seven level electrical converter for single section system. The modulation technique will be simply extended to 3 section system. Simulation work is completed exploitation the MATLAB code. an in depth analysis is completed on diode clamped seven level electrical converter and experimental results ar conferred to demonstrate the prevalence of the planned system. That dissects the frequency spectrums of the traditional and therefore the planned schemes ar compared with one another through simulation.
