Power Inverters from 5KVA to 2.5MVA

Solid State Power Inverters

PCTI power inverters and converter capabilities can support any combination of AC or DC inputs and outputs falling within the general parameters indicated below. DSP control and monitoring can also allow for universal AC inputs to accommodate a wide range of inputs spanning the variety of global distribution services. PCTI power inverters are solid state insulated-gate bipolar transistor (IGBT) based on DSP PWM (digital signal processor, pulse width modulated) technology. We are a regular manufacturer of DC to AC power inverters, AC to DC power inverters, industrial power inverters, and military power inverters.

For Your Application

PCTI can provide the power inverters and converters you need for your specific application, whether you need to change DC or AC to another or change the frequency. PCTI power inverters are digital signal processor (DSP) controlled based on IGBT PWM technology. This superior, next-generation control allows us to provide a single control board solution for the inverter, thus increasing reliability by reducing control components. Whether you need a high quality AC waveform suitable for sensitive electronic equipment, or some other purpose, contact PCTI about power inverters for more details. If you need help in specifying your inverter, request a quote online, or download our inverter brochure.
