In the high speed rail system, the distortion of the voltage and the current waveform of the input power line, increases the power loss and make a several electro-magnetic problems such as EMI or the interference of the communication line.<br/> In this paper, the control scheme of the PWM converter to make a good power factor and to regulate the output voltage as well as to reduce the harmonic component of the input current is proposed. Also a control schem of the PWM converter in the parallel operation to reduce the harmonics of the input current is proposed<br/>
