Hi, I am currently studying PFC circuits and there is something that is not clear for me, the output of a boost-PFC stage is usually specified with something like: Vout=400V, Iout=500mA. My question is, does this mean that the RMS of input current of the following stage, let's say a flyback converter, should not exceed 500mA ? this sounds wierd because I am sure RMS current of such converters could surpass this value in many power supply applications. Can any one help me understand this please ?
