Switch Mode Power Supply (SMPS) Topologies
ww1.microchip.comSep 10, 2007 · Switch Mode Power Supply (SMPS). There are several ... of a DC-to-DC converter, as shown in Figure 1. The load, ... As shown in Figure 1, the output voltage V OUT can be regulated by varying the series resistor (RS) or the shunt current (IS). When VOUT is controlled by varying IS and keeping RS constant, power loss inside the converter occurs. This

W1TS VINTAGE TRANSMITTER - ARRL - Home
www.arrl.orgIf the input capacitor (0.01 mF) to the network were to fail, high-voltage DC would be applied to the transmission line, antenna, and the various plate circuit components. Should this occur, the choke provides a DC ground connection, shorting the power supply output and blowing the fuse! S2 provides simple manual transmit/receive (T/R) switching.
