Abstract
Abstract. In the area of photovoltaic application of multilevel cascade H-bridge inverters (CHB) has been widely used recently. In this paper a new procedure for space vector modulation has been proposed which significantly reduces amount of mathematic calculation. The proposed procedure is simplified and considerably overcomes a number of problems as a result of complex equation for finding appropriate vectors. This technique does not reduce the output voltage qualifications and efforts involved in selecting suitable vectors of a seven level inverter. New proposed SVM scheme is discussed and detailed that simulation results are provided for a seven level inverter with 1kW and 220V nominal value. The value of the proposed technique is demonstrated experimentally by applying the novel SVM approach to a conventional multilevel inverter.
