An IGBT integrated power module for configurable series/parallel operation at high power and frequency

Summary form only given. Eagle Harbor Technologies (EHT) has developed a modular solid state power supply based on IGBT technology which can support a wide array of applications. The EHT Integrated Power Module (IPM) incorporates fast gate drive technology, high voltage isolation (~ 30 kV), fiber optic control, and optional crowbar diodes into a single unit. Modules are designed for pulsed/burst operation at frequencies up to 2 MHz. For a 10 ms 100 kHz pulse width modulated (PWM) burst, the modules have a nominal 1 kV at 2.5 kA output. Currents up to 10 kA can be switched for shorter periods. The modules can be stacked in series and/or parallel arrangements as needed to obtain higher voltages and currents. The EHT IPM utilizes off the shelf IGBTs that reduce cost while allowing a great deal of flexibility for output voltage, current, switching frequency and efficiency by simply choosing the correct IGBTs for the desired application.
