Energy—Big voltage, little package
Oak Ridge National Laboratory's new Stinger Energizer provides voltages exceeding 100 kilovolts in a compact highly efficient, portable package, making it ideal for laser systems, X-ray units, particle accelerators, electrostatic purifiers, copy machines, bug zappers and many other products. Conventional high-voltage power supplies consume significantly more power, are heavier and at least 10 times larger. The Stinger, developed by a team led by Bruce Warmack, operates by transforming a low direct current voltage of 3.3 volts to 24 volts to a high-frequency alternating current voltage up to 12 kilovolts. A series of high-voltage diodes and capacitors are specially arranged in a stack that is just two inches in length to provide 120 kilovolts.
