In this paper a five-level PFC boost rectifier is presented. .This rectifier has less active semiconductor switches, due to this switching losses and number of required gate drives are reduced. The proposed topology is controlled by sliding mode controller. Sliding mode controller is designed to regulate the output DC voltage and to ensure unity power factor mode of the input AC voltage and current. Multicarrier PWM technique has been used to produce switching pulses from control signal. Five level voltage waveform harmonics has been analyzes conclusively that affects the size of input current and required filters directly. Moreover, low harmonic AC current waveform has been achieved by the implemented controller and employing a small inductive filter at the input line. This topology correcting the power factor while delivering power from AC grid to the DC loads and also reduces the current and voltage harmonics. Simulation is done in MATLAB/SIMULINK and results of simulation and hardware shows the waveform of power factor correction and current and voltage harmonics reduction for resistive load.
