Abstract

A simple low-cost analog controller is proposed for average current mode control of high-power-factor boost rectifiers operated in the discontinuous conduction mode (DCM). The current shaping is based on comparison of the input current with a suitably generated periodic nonlinear carrier. The controller does not need input voltage sensing, error amplifier in the current-shaping loop and/or any multiplication/division operation. The performance of the proposed controller is close to those of existing schemes. The controller may be fabricated into a single integrated circuit. A 600W rectifier is simulated in MATLAB/SIMULINK. The control concept is experimentally validated on a 600W laboratory prototype.
