PowerStack Inverter Selection Guideand Matrix
The APS PowerStack series of high power IGBT inverters offer a complete, fully integrated solution for your requirements. Just add power and GO!Our standard and custom PowerStack Series of Single Phase and Three Phase High Power IGBT Inverters are available with all the features needed to get your project up and running fast.
APS's PowerStack IGBT Inverters integrate laminated bus bars, IGBT Gate Drivers, and Protection Circuits in a single compact package.
These PowerStack High Power Inverters have a number of important options, including:
- Air-Cooled Heatsinks - Copper and/or Aluminum• Liquid Cooled Chill Blocks• High Power Capacitor Banks / IGBT Snubber• Full-control, half-control or diode front end converters on a common heatsink assembly• Dual inverters on a common heatsink assembly• Soft-Start circuits• Other circuits and current levels available on request
The PowerStack is a flexible, highly integrated IGBT based high power inverter assembly with a wide range of applications. These include inverters for motor controls, switch mode power supplies (SMPS), UPS, welders, etc. The PowerStack can be operated at frequencies up to 20kHz. The PowerStack can be configured as a three phase bridge inverter mounted on a heatsink with optins for air or liquiquid cooling. Configurations include options for (full, half or no control) converter input circuitry, inverter output circuitry, cooling and a wide variety of drivers and safety features for the converter front end and IGBT inverter output stage. To operate at high switching frequencies, the PowerStack utilizes a low inductance laminated bus structure, optically isolated or fiber optically coupled gate drive interfaces, isolated gate power supplies and a DC-link capacitor bank.The PowerStack provides built in protection features including: OverVoltage, UnderVoltage lockout, OverCurrent, OverTemperature, short circuit and optional airflow or liquid flow indicators. Flexibility is a key feature of the PowerStack . Options include: a choice of converter front ends, rectifier, half or full SCR control, with or without SCR gate firing boards and soft-start circuitry. Customer provided PWM is optically coupled or a fiber optic link can be provided to the IGBT interface. Current feedback is provided by Hall effect current transducers.
