Abstract:
A power supply for producing a single level D. C. output voltage in response to a 110 or 220 A. C. input voltage is disclosed. The power supply automatically selects a full wave diode bridge or voltage doubler configuration and provides series capacitors to filter the D. C. output voltage. The selection is controlled by a switch which responds to the charge on one of the output capacitors. Latching means are also provided to prevent the power supply from switching to the voltage doubler configuration once 220 volts is applied.
+ Using a plasma "wind tunnel" at Swarthmore College, professor Michael Brown and post doc David Schaffner are now able to simulate the key signatures of magnetic turbulence seen in the solar wind and expected to play a role in astrophysical jets driven by exploding stars.
