Integrated Power Product Assemblies

POW-R-PAK™ IGBT Assembly


The Powerex POW-R-PAK™ is a configurable IGBT based power platform that can be used for quick and easy product feasibility testing, rapid prototyping and design validation. POW-R-PAK systems are suited for energy storage, uninterruptable power supplies (UPS), motor drives, solar, wind, photovoltaics, EV and hybrid electric vehicle applications. The power assembly is mounted on a forced air-cooled heatsink and features state-of-the-art Powerex IGBTs with low conduction and low switching losses for high efficiency operation. The POW-R-PAK includes a low inductance laminated bus structure, optically isolated gate drive interfaces, isolated gate drive power supplies, and a DC-link capacitor bank. The interface board provides simple user connections along with built-in protection features including overvoltage, undervoltage lockout, overcurrent, overtemperature, and short circuit detection. The POW-R-PAK is available for operation with DC bus voltages of up to 800VDC (1200V assembly); DC bus voltages of up to 400VDC (600V assembly); switching frequencies below 20kHz.
