A gate drive printed circuit board (PCB) was developed for a 50-mm-wide modular-design thin power unit that uses two double-sided cooled power modules in an uninterruptible power system (UPS). A conventional gate drive PCB has a concentrated gate power supply circuit that uses a large transformer and has a conventional pulse open-phase detection circuit that occupies a large mounting area. Thus, the...
To improve the insulation reliability of insulated metal substrates for power modules, we propose an insulated metal substrate that has a porous alumina anodic oxide film along the interface between an aluminum base and resin insulating layer. By having two anodic oxide films, i.e., inorganic and organic acids, compared with conventional substrates, the proposed substrate improves the adhesiveness...
Realizing a sustainable society will require a reduction in CO2 emissions, and many different sectors of the economy are being encouraged to be energy efficient, including the electric power business, industry, and consumer and transportation businesses. In the transportation sector in particular, environmentally conscious vehicles that use power electronics will be essential as replacements for conventional...
Direct Water and Double-Sided Cooled Power Modules (DWDSCPM) are especially attractive due to high thermal performances. The DWDSCPM was able to reduce the thermal resistance by 50% and increase power density of the traction inverter by 70% in comparison with a conventional power module.
