Mitsubishi DIPIPM: Intelligent Power Modules for Commercial Air Conditioning
Mitsubishi Electric has maintained an absolute advantage in the variable frequency home appliance market since launching the DIPIPM (Dual In-line Package Intelligent Power Module) in 1997. For commercial air conditioning systems, the company offers a comprehensive range of DIPIPM and SLIMDIP modules that enable energy-efficient compressor motor control with integrated drive and protection circuitry.
Large DIPIPM+ for Commercial Multi-Split Systems
The Large DIPIPM+ series is specifically designed for commercial cabinet and multi-split air conditioning systems. Rated at 50A to 100A with 1200V voltage capability, these modules incorporate 7th generation CSTBT silicon chip technology. Each module integrates the rectifier bridge, inverter bridge, and drive protection circuit in a single package, with built-in short-circuit protection, under-voltage protection, temperature analog output, and bootstrap diode functionality. This high level of integration simplifies system design and reduces component count for commercial air conditioning manufacturers.
SiC SLIMDIP for High-Efficiency Residential and Light Commercial Systems
The SiC SLIMDIP series represents the latest advancement in intelligent power modules for air conditioning applications. The full SiC variant (PSF15SG1G6) reduces power losses by approximately 79% compared to silicon equivalents, while the hybrid SiC variant (PSH15SG1G6) achieves approximately 47% loss reduction. Both modules maintain complete package compatibility with existing silicon-based SLIMDIP modules, enabling drop-in upgrades for improved energy efficiency without mechanical redesign.
Compact DIPIPM for Mid-Range Commercial Units
The Compact DIPIPM series, available in 30A/600V and 50A/600V ratings, utilizes 3rd generation RC-IGBT technology. The package size is reduced to 53% of the Mini DIPIPM, enabling more compact air conditioning unit designs. A new bridge arm short-circuit protection interlock function enhances system safety, and the operating temperature lower limit is extended to -40C, suitable for cold-climate commercial HVAC applications.
Ultra-Compact Full SiC DIPIPM
For the highest efficiency requirements, Mitsubishi Electric offers ultra-compact full SiC DIPIPM modules (PSF15S92F6-A6 at 15A/600V and PSF25S92F6-A6 at 25A/600V). These modules integrate SiC MOSFET chips with high turn-on threshold voltage, eliminating the need for negative voltage bias. Single-channel DC18V power supply drive simplifies the gate drive circuit, and pin compatibility with 6th generation products facilitates easy adoption in existing air conditioning platform designs.
Industry Recognition and Future Development
Mitsubishi Electric’s DIPIPM technology has earned industry recognition, including the Quality Leadership Award from Haier Smart Home for providing SLIMDIP products in variable frequency air conditioners and washing machines. The company is accelerating development of 7th generation DIPIPM with extended temperature ranges, ensuring continued advancement in commercial air conditioning energy efficiency and motor control performance.
