Mains harmonic currents into SMPS are too large?

Hello,

I have designed a 330W SMPS which runs off 90VAC via a voltage doubler. (it has no PFC because its for audio)

I have done an equivalent simulation so as to calculate the mains harmonic currents.

I am getting 5.73 Amps at the third harmonic current level....how can this be?

Here is my mains input current:-

......it is 3.5 Amps RMS

Here is the FFT of the above mains input current:-

...the third harmonic is shown to be 4.31dB which represents 5.73 Amps RMS

calculation = 20log([3rd harm]/3.5) = 4.31dB
...then work out "3rd harm" from this, it comes out as 5.73 Amps

here is the LTSpice simulation schematic....which is just a "token" SMPS which draws 110W constant power.

-So howcome i have this huge 3rd harmonic current? , which would fail me on the approvals testing
