MATLAB/Simulink based Three-Level Integrated AC-DC Converter with pulse width modulation (PWM) technique is presented in this paper. Internally the proposed converter has two individual converters, one is at input side (called as an input converter), which is for power factor correction purpose the and another one is at DC output voltage (called as output converter), which is for regulation purpose of the output DC voltage. The proposed converter with its two internal converters integrates the operation of the boost power factor correction and the three-level dc–dc converter and one more advantage with the input converter is prevents the dc-bus voltage from excessive voltages. The time constant for PFC controller should be faster in compare to output voltage controller. The resultant simulation waveforms justify AC-DC conversion operation efficiently.
