Custom High Voltage Power Supplies

4 kHz, 20 kW
A 4-kilohertz repetition rate, water-cooled, 20-kilowatt average power, capacitor charging high voltage power supply. The compact 3.0 kV power supply provides excellent precision and pulse-to-pulse repeatability, rapid response to programmed changes in output voltage, and many other features required by this demanding application. This design represents a number of “firsts” for General Atomics Energy Products:

20 kW average power in a single rack-mounted enclosure
4 kHz pulse repetition rate capability
0.2% pulse to pulse repeatability
Water-cooling

15 kJ/s, 26 kV
High Voltage Power Supplies provided to Lawrence Livermore National Laboratory for the National Ignition Facility (NIF). The 400 custom 15 kJ/s, 26 kV power supplies are configured so that each 2 MJ capacitor bank is charged by 2 parallel power supplies in slightly over 1 minute.

12 kJ/s, 65 kV
High Voltage Power Supplies provided to the Los Alamos National Laboratory's ATLAS program. The 96 custom-designed power supplies are comprised of 48 each positive polarity, 12 kJ/s, 65 kV power supplies and 48 each negative polarity, 12 kJ/s, 65 kV power supplies.

The oil-insulated AC/DC switching power supplies are used to charge large energy storage capacitors in 24 Marx Generator Modules. The Marx capacitors are charged to ±60 kV and then discharged in series to deliver a pulse of high peak power used for high-energy physics experiments.

20 kJ/s, 7 kV
High Voltage and High Power Switching Power Supplies used at the High Energy Laser Systems Test Facility, (HELSTF), located at White Sands Missile Range, New Mexico. GAEP designed and built 80 custom 20 kJ/s, 7 kV capacitor charging power supplies for the U.S. Army's 100-kW diode-laser-pumped solid-state high energy laser development.

20 kJ/s, 1.5 kV
High Power Switching Power Supplies used in the Advanced Linear Motor Project. The 20 kJ/s, 1.5 kV, air insulated capacitor charging power supplies charge a single shot capacitor bank with a duty cycle of 40 seconds on, 15 minutes off.

10 kJ/s, 50 kV, 300 VDC Input
High Voltage and High Power Switching Power Supplies with a DC input of 300V. The 10 kJ/s, 50 kV, oil insulated capacitor charging powers supplies have an efficiency greater than 90%.
