This really is deceptive, While I'm absolutely sure there's a cause of that.

The truth is, it could possibly incorporate techniques that straddle zero but present some sub-threshold voltage of a problem duration. I had been surprised to view science imitating art so perfectly in your "bottom in the barrel" waveform. Not all Energetic PFC power supplies will have issues เครื่องสํารองไฟ server with all non-sine wave UPSs, but some don't operate with each other and this is the cause why. +one to the science.
