Power Inverters from 5KVA to 2.5MVA


PCTI can provide the inverter/converter you need for your specific application whether you need to change DC or AC to another or change the frequency. PCTI 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.

Our power inverters are built to customer order based on our standard designs and offer high performance, high reliability and sophisticated control systems. Applications include remote power stations, grid tie in systems (including dc power supplies for grid tie systems), microgrids, renewables including wind, solar, fuel cells, transportation, backup power, overhead cranes, as well as many others. A variety of computer interfaces are available to meet all of your inverter programming and control requirements.

General Inverter Specifications

PCTI inverter 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 IGBT based on DSP PWM (digital signal processor, pulse width modulated) technology.
