Configurable Power

The PowerStack from Applied Power Systems is a configurable IGBT based power stage that may be used as a converter, chopper, half or full bridge, or three phase inverter for motor control, power supply, UPS or other power conversion applications.

The IGBTs for the power assembly are mounted on a forced air-cooled or water cooled heat sink. The switching devices interface with a capacitor bank via a low inductance laminated bus. The gate drive board provides a simple user interface along with protection features including: overvoltage, overcurrent, undervoltage lockout, overtemperature, and short circuit protection.

Depending on application characteristics, the PowerStack is suitable for operation with DC bus voltages up to 800 VDC and switching frequencies above 20 KHz.
