Actually, he is likely thinking the RMS calculation of which 120VAC RMS would be 120 x 1.414 = Peak voltage and Peak voltage x .707 to get RMS. You would be much closer using the 120 x .707 to get a well filtered DC voltage.
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: February 8, 2003 4:33 PM To: biofuel@yahoogroups.com Subject: [biofuel] AC -> DC I am looking at WVO fueled diesel powered home/shop co-generation options. The thinking process came up a design idea where some 120VAC would be converted to ?VDC. Someone I respect in electronics stated that a simple AC -> DC filtered rectification circuit results in the output VDC being 1.7 the input VAC. This does not seem right to me and while I could go buy the components to test the hypothesis, I would prefer someone either confirm or refute the x1.7 claim. I searched the internet and my books without success; so, I pose it here as defined: ac_dc.jpg If input is 120VAC, then will the output be = 120VDC, x1.7 = 204VDC, or = something else? Assume simple filtering by capacitors and inductors with reasonable component quality as this is more theoretical than absolute precision real-world design at this stage. Personally, I would think it would be 120VDC while if it were 204VDC it would be very nice for my application. Maybe someone knows a good web site to provide the answer to this simple electricity circuit.
