PCTI - DC Power Supplies, Frequency Converters, Battery Chargers and Inverters

Power Conversion Technologies, Inc. (PCTI) has been providing leading-edge power electronic solutions to military, aerospace and commercial industrial customers since 1992. Our power conversion systems operate in numerous military applications including missile launch control, communication systems, mobile ground support, backup battery systems, submarine battery charging, weapons laboratories, shipboard frequency conversion and many others. PCTI manufactures both standard and custom power electronics for all branches of the DOD as well as prime contractors such as Boeing, Raytheon, General Dynamics, and BAE Systems.

PCTI POWER CONVERSION PRODUCTS

PCTI’s products address the highest power range of power electronic equipment available from 2KVA/KW to 15MVA/MW. We offer a variety of modular standard products, Mil-Spec products and custom designed equipment for your application. Options may include computer interfaces (IEEE 488.2, RS232, RS485, GPIB) and cooling methods such as forced air, heatpipe, direct water, closed-loop water-to-water heat exchanger and natural convection. Applied technologies include high-frequency switched mode designs, DSP control, PWM, and IGBT technology. Our product scope includes:

• High current battery chargers (switched mode or linear)
• Inverters DC/AC, DC/DC, AC/DC and AC/AC
• Frequency converters, 50Hz/60Hz to 400Hz, 50Hz to 60Hz, 60Hz to 50Hz
• DC power supplies / rectifiers high-current, low voltage (switched mode or linear)

HIGH CURRENT BATTERY CHARGERS

PCTI offers rugged high-current battery chargers to meet all of your high-current industrial charging applications in all standard voltages with current ratings from 25A to 2,000A. Our battery chargers are offered using classic linear or switched mode technology providing a smaller, lighter battery charger.

Our standard battery charger includes a battery eliminator, float and equalize adjustments, manual equalize timer, automatic shutdown and restart. Options include computer interface, discharge capability, temperature compensation circuit and more. PCTI battery chargers are used in a number of critical applications including backup power for control relay stations in hydroelectric dams, submarine battery charging.

INVERTERS

PCTI can provide the inverter you need for your specific application whether your application is DC/AC, DC/DC, AC/DC and AC/AC or you need to change the frequency. PCTI inverters are digital signal processor (DSP) controlled based on IGBT PWM technology delivering a pure sine wave with less than 1% THD and 90% or better efficiency. This superior next-generation control allows us to provide a single control board solution for the inverter, thus increasing reliability by reducing control components. It also permits us to offer a universal DC input from 300VDC to 700VDC. Power ranges include from 1kVA/KW to 500kVA/KW.

FREQUENCY CONVERTERS

PCTI frequency converters can be used for 400Hz aircraft ground support, convert 50 to 60Hz or converter 60Hz to 50Hz. PCTI frequency converters are digital signal processor (DSP) controlled based on IGBT PWM technology delivering a pure sine wave with less than 2% THD and 90% or better efficiency. This superior next-generation control allows us to provide a single control board solution for the inverter, thus increasing reliability by reducing control components. Our 400Hz frequency converters meet the standards of MIL-STD-704F, MIL-STD-461, and MIL-STD-810.

DC POWER SUPPLY (RECTIFIERS)

PCTI's regulated DC power supplies are a solid-state unit utilizing primary SCR (thyristor) technology in a full-bridge rectifier or switched mode IGBT based on DSP PWM technology, constant voltage control, constant current control, automatic crossover series regulation, DC filter, instrumentation, and many operational and protective monitoring features. Power supply designs are available in ratings from 1kW to 15MW with current ratings up to 120kA. PCTI also offers switched mode technology up to 100kW without paralleling.
