Revolutionizing Power Solutions in Electric Vehicles
ROHM Semiconductor is making significant strides in the field of electric vehicle (EV) technology with the announcement of its cutting-edge 4-in-1 and 6-in-1 SiC molded modules. These innovative products are designed for use in PFC and LLC converters, particularly in onboard chargers (OBC) for electric vehicles. With six models rated at 750V and seven models rated at 1200V, the HSDIP20 package integrates all essential circuits for power conversion, drastically simplifying the design process for manufacturers.
The Need for High Power Density
The transition towards a decarbonized society is driving the electrification of automobiles, which presents unique challenges. The demand for longer cruising ranges and faster charging in electric vehicles has led to an increase in battery voltages. Consequently, this escalates the demand for enhanced power from OBCs and DC-DC converters. Manufacturers are now pushed to deliver not only higher outputs but also more compact, lightweight solutions. ROHM's latest development meets this need by offering superior power density along with exceptional heat dissipation features.
Addressing Technical Challenges
One of the standout features of the HSDIP20 package is its insulating substrate that excels in heat dissipation. This ensures that chip overheating is minimized, even during high-power operation. In comparative tests involving a standard OBC PFC circuit utilizing discrete SiC MOSFETs, ROHM’s 6-in-1 module demonstrated a temperature difference of approximately 38°C cooler at a power output of 25 watts. Such advancements not only enhance the efficiency of the module but also allow for handling higher currents within a compact form. As a result, the HSDIP20 reduces the required mounting area by about 52% when positioned against traditional top-side cooled configurations, ultimately supporting the miniaturization of power conversion circuits.
Future Directions for ROHM
ROHM Semiconductor is set to continue its innovation journey by further developing SiC modules that blend high efficiency with compact design. The company is also placing emphasis on creating automotive SiC Integrated Power Modules (IPMs) which promise higher reliability while occupying less space. This continual evolution is crucial in facilitating the widespread adoption of electric vehicles.
Application Examples Across Industries
The versatility of ROHM's HSDIP20 package is evident across various sectors. In automotive applications, it caters to onboard chargers and electric compressors, ensuring efficient energy use. Meanwhile, in industrial settings, this innovative module is poised to enhance electric vehicle charging stations, vehicle-to-everything (V2X) systems, server power supplies, and more.
