ABSTRACT:
The bridgeless boost topology reduces the power dissipation, cost, and size of prior PFC systems by eliminating the intrinsic loss of the input rectifier bridge. Sensing of the input line voltage by the controller is unnecessary. The use of One Cycle Control (also known as Single Cycle Control) allows the Power Factor Correction function to be performed without complex rectification networks to obtain the AC line voltage reference. The use of bi-directional switches makes it possible to control inrush current (the startup over-current due to the charging of the output bulk capacitor), which allows elimination of over-current limiting devices and reduction of the diode surge capability requirements. Moving the boost inductor to the system input adds an additional filtering function, reducing the cost of input EMI filtering.
