Universal DC-to-DC Converter - This circuit will generate a smaller DC
output voltage from a larger DC input voltage.It is quick and simple to make and by
changing the value of the zener diode, the circuit can be universally adapted to
provide other output voltages.The circuit and all diagrams represent a DC convertor
with 12V battery input and 9Volt DC output.(electronic schematic / circuit added 4/02)

Variable 3 - 24 Volt / 3 Amp Power Supply - This regulated power supply can
be adjusted from 3 to 25 volts and is current limited to 2 amps as shown, but may be
increased to 3 amps or more by selecting a smaller current sense resistor (0.3 ohm).
The 2N3055 and 2N3053 transistors should be mounted on suitable heat sinks and the
current sense resistor should be rated at 3 watts or more. Voltage regulation is
controlled by 1/2 of a 1558 or 1458 op-amp. The 1458 may be substituted in the circuit
below, but it is recommended the supply voltage to pin 8 be limited to 30 VDC, which
can be accomplished by adding a 6.2 volt zener or 5.1 K....….Page has several
circuits, please scroll to find this one. [Bill Bowden's website] |

Variable load tests voltage sources - 19-Jul-01 Issue of EDN The
circuit in Figure 1 serves as a variable, current-sink load for testing voltage
sources. You use digital commands to set the load current of the device under test
over a wide range, independent- ly of the device under test's output voltage. The
circuit comprises an AD558 DAC, IC1, which provides a reference voltage at Point A....
