摘要
Bridgeless boost PFC circuits and systems providing an improved method of current sensing using two current sensing resistors is envisaged. Analog switches are provided to select one of the two current sensing resistors based on the polarity of the AC line. An amplifier is provided to eliminate use of resistors with large values, thus resulting in lower power loss and efficient systems.
