This paper present cascade multilevel inverter using Sine PWM and Inverted sine PWM control strategy. The main advantages of these multilevel inverters is that they generate very less harmonics as compare to conventional inverter. This makes it very useful in the area of control and energy distribution, static reactive power compensation and adjustable-speed drives. This paper also present new PWM control strategy, called inverted sine PWM control strategy. This Inverted sine PWM control strategy generate very less Total Harmonic Distortion (THD), and switching losses as compare to conventional sine PWM control strategy, also This ISPWM method reduces the number of carriers as compare to conventional sine PWM method, so it increases the fundamental output voltage even modulation index is less This paper compares the % of THD for all level shifted and phase shifted sine PWM and inverted sine PWM control strategy of voltage and current for cascade multilevel inverter. The simulations for the five level cascade multilevel inverter using both inverted sine and sine PWM control strategy are carried out in MATLAB® software.
