How? In a classical PFC design, the controller output (current demand) is multiplied with the rectified input voltage used as a sine waveform reference to generate a variable sine waveform current setpoint. I don't see, how a CMOS switch should perform this task.
Thanks to replying,
I see some book about the one quadrant multiplier,but I can't clear, who have referring to paper,and send to me, Thank you very much!!!! My mail :0917zxg@163.com
I think, multiplier building blocks are among the basic analog IC "ingredients" that are discussed in profound text books. I wouldn't expect specialized books about each of it. In case of a PFC, the multiplier requirements won't be particularly critical. It's more a question of minimizing the effort. So a differential pair operated as basic "gm" (transconductance) multiplier should do the job.
I have used only simple multipliers as synchronous detectors. I have here an old
"IC-OPAMP Cook Book " by W.G. JUng, SAMS 1994: there are two four-quadrant multipliers described, one with Motorola 1495, another with AD534.
I think those are now obsolete; please look at "www.analog.com", they have updated components and also White Papers on how to best use them.
