January 18, 2007[Ideas For Design] Simplified AC Line Sensor Uses Few Parts, Little Real Estate
Typically, ac line sensors use comparators. But I had to design a power supply to be as low in cost as possible, be self-powered, use through-hole components, and take up as little space as possible on a small two-sided pc board. So I developed the simplest ac sensor possible. The resulting circuit senses the high-voltage dc bus (...
August 3, 2006[Ideas For Design] Averaging Improves Regulation Of Second Power-Supply Output
A switching power supply's main output usually will have a load regulation of better than 0.1%. However, what if it doesn't need regulation that tight on the main output, but instead needs better regulation on a second output? The averaging technique described here eliminates the need for adding linear regulators to achieve better regulation on the second output, reducing cost and parts count. Figure 1 shows a typical switching regulator....
