摘      要：This paper presents an efficient supply current wave shaping technique for bridgeless interleaved Single Ended Primary Inductor Converter(SEPIC).The SEPIC converter converts an Alternating Current(AC)to Direct Current(DC)with the boost *** Factor Correction(PFC)is progressively significant to achieve high energy *** overall system efficiency can be increased as the bridgeless topology has less conduction losses from rectifying ***,the bridgeless and interleaved techniques are incorporated in this study to achieve better *** performance of the system is analyzed on both current control and sensor-less *** controllers such as Proportional Integral(PI)control,peak current control,Non-Linear Carrier(NLC)control,and sensor-less current control are *** the above controllers are implemented using MATrix LABoratory(MATLAB)/*** performance parameter,namely Power Factor(PF),Total Harmonic Distortion(THD),is computed for both open loop and closed loop *** sensor-less current control method is implemented using the DsPIC30F2010 *** circuit performance is also verified from the simulation and hardware *** proposed controller has inbuilt Analog-to-Digital Converter(ADC),Digital-to-Analog Converter(DAC),Pulse Width Modulation(PWM)generator,and provides fast responses.
