Fast-Recovery Circuitry And Method For A Capacitor Charging Power Supply

US Patent:
2006007, Apr 6, 2006
Filed:
Sep 30, 2004
Appl. No.:
10/955256
Inventors:
Steven McCool - Austin TX, US
Rens Ross - Austin TX, US
David Gwinn - Lowell MA, US
Steven Schmidt - Round Rock TX, US
Assignee:
Nanotechnologies, Inc. - Austin TX
International Classification:
H02J 7/00
US Classification:
320116000
Abstract:
A power supply with a high voltage current regulated output wherein input devices are gated ON and OFF to regulate the output current. The output current is coupled through a current limiting inductor to a high voltage fast electronic switch (E-switch) that turns ON and OFF much faster than the power supply can shut down. The electronic switch is bypassed with a resistor network that is sized to dissipate slightly in excess of the full power rating of the power supply during a shut-down cycle. The electronic switch is normally gated ON providing a low impedance path for current charging the capacitor bank. When a short circuit condition is sensed, the E-switch is turned OFF and the resistor network limits the short circuit current, limits the voltage across the E-switch, and dissipates any energy stored in the inductor and the power supply circuitry during power supply shut-down.
