A Predictive Switching Modulator for Current Mode Control of High Power Factor Boost Rectifier
نویسنده
چکیده
In this paper, a new variation of current mode control for high power factor Boost rectifier is presented. The general features are no input voltage sensing, no use of multiplier, and no inner current regulator. It therefore follows the same control structure as that of Linear Peak Current Mode Control (LPCM) and Non Linear Carrier Control (NLC) . However it implements a different equation for the modulator that extends the range of continuous conduction mode (CCM) of operation. The controller is predictive as the actual current equals the reference current at the end of each switch period.

This paper presents a sliding mode space vector current modulator for three-phase single stage AC/DC Buck-boost rectifiers. Using this fast and robust control method, this type of converters draw near sinusoidal input currents with high power factor. A Proportional Integral (PI) controller can, then, be adopted to regulate the rectifier output voltage. The references of the sliding mode current...
