Abstract:-The equipment connected to an electricity distribution network usually needs some
kind of power conditioning, typically rectification, which produces a non-sinusoidal line current
due to the nonlinear input characteristic. Pulse width-modulated (PWM) rectifier technology is
increasingly used in industrial applications like variable-speed motor drives, since it offers several
desired features such as sinusoidal input currents, controllable power factor, bidirectional power
flow and high quality DC output voltage. Recently, however, new control approaches analogous to
the well-established direct torque control (DTC) methodology for electrical machines have
additionally emerged to implement a superior PWM rectifier. This approach is predicated on
phase shifting of 2 boost converters connected in parallel and dealing at a similar switching
frequency. The PI controller is employed to reshape the input current therefore on reduce the
harmonics. The input EMI filter is inserted in the projected strategy thus as to reduce the effects of
switching harmonics.
