Implementation of Three phase SPWM Inverter with Minimum Number of Power Electronic Components

In the past decades, the researchers have dealt with the conventional topology, which possesses sum switches of Multilevel Inverter is applied to PWM method. The present research work has been introduced a new method of multilevel inverter using reduced switches is applied with PWM technique. In introduction part the conventional new multilevel inverter & switching pattern are explained. In second part PWM technique of proposed work and circuits is explained. The width of this pulses are modulated in order to obtain inverter output voltage control and to reduce its harmonic content. Sinusoidal pulse width modulation or SPWM is the most common method in motor control and inverter application. Conventionally, to generate the signal, triangle wave as a carrier signal is compared with the sinusoidal wave, whose frequency is the desired frequency.
