Mitsubishi Electric Corporation is introducing its new “PV Series” of intelligent power modules (IPMs), which is mainly intended for use in residential photovoltaic (PV) inverters. The six different modules which are also well-suited for inverters in fuel cell systems, are integrated in packages with a footprint of just 90mm x 50mm.

Compared to Mitsubishi Electric's current PV series IPMs, which were launched already in 2005 these new modules require 30% less board space. Therefore, the new PV IPMs from Mitsubishi Electric provide a significant contribution to making PV inverters smaller.

In order to suit the various types of IPMs needed in PV inverters Mitsubishi Electric has developed six different modules within its new PV IPM series. This means that the new devices are well-suited for single-output inverters without chopper or with one or two choppers.

All the devices are rated for a collector-emitter voltage of 600V with a collector-emitter saturation voltage of VCE(sat) = 1.9V (typ.) @ Tj = 25°C and a FWDi forward voltage of Vf = 1.7V @ Tj = 25°C. While the models PM50B4L1C060 (inverter part only), PM50B5L1C060 (+ 1 chopper) and PM50B6L1C060 (+ 2 choppers) are specified for collector currents of 50A, the models PM75B4L1C060 (inverter part only), PM75B5L1C060 (+ 1 chopper) and PM75B6L1C060 (+ 2 choppers) are specified for collector currents of 75A. All IPMs are protected against short circuit, undervoltage and overtemperature.
