How To Determine Power Supply Transformer Ratings
applicable to dual complementary circuit. Consider an example of a dual output power supply with 15VDC @ 800mA. Thus, Vout = 15V, Vreg = 3V, Vrect = 1.25V, Vripple = 0.75V (1.0V P-P) Therefore, VAC = 38 V with center tap; IAC = 1.8 x 800 = 1.44 Amps r.m.s. Thus the transformer secondary rating can

Arthur G. Russell Co. and NTI Announce a Dual Break Through in Nano Fiber Production using New Die Design and Inexpensive Polymers.
Dateline Thursday October 1, 2009 A series of tests at University of Tennessee lab under the direction of Dr. Gajanan Bhat produced nano-fibers in PP and two polyesters, PET and PBT. The latter are inexpensive fibers never before melt blown into nano-fibers so far as is known. The die was designed
