Configurable Power

The IAP-600T120 PowerStack is a flexible, highly integrated IGBT based power assembly with a wide range of applications. These include inverters for motor controls, switch mode power supplies (SMPS), energy storage, renewable energy, UPS, welders, etc. The IAP600T120 PowerStack can be operated at frequencies to over 20kHz. The IAP600T120 PowerStack is configured as a three-phase bridge inverter mounted on an air-cooled or liquid-cooled heat sink. 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 IAP600T120 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 IAP600T120 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 IAP600T120 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. A choice of cooling methods, forced air or liquid is also available. 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.

The IAP600T120 PowerStack is rated to maximum input voltages up to 800 VDC, switching frequencies to over 20kHz, includes many safety features to protect the IGBTs and output circuitry and can be configured to meet your application.
