This paper proposes a four times DC-link voltage PWM power converter, which is constructed by four cascade connected power switching devices such as IGBT These four switching devices are controlled by a sinusoidal PWM method to obtain a DC-link voltage which IS higher than 4 times the peak supply voltage, and to suppress input current harmonic components achieving a sinusoidal current waveform with less than 3[%] distortion. Which is also constructed by four cascade connected IGBT<br/> by the Simulation result
