SiC Solutions for the Energy Infrastructure Market

The energy infrastructure market which consists of applications such as Solar Inverters, Energy Storage Systems, EV Charging Stations, and Uninterruptable power supplies is undergoing a transition to Silicon Carbide (SiC) power semiconductors from traditional silicon (Si) power semiconductors. The advantages of SiC FETs compared to IGBTs in these applications will be explored in addition to the trends in these markets that are accelerating this transition. As these are high power applications a comparison between discrete and module solutions will also be analyzed. Lastly, whether a discrete or module is used gate drivers will be needed and thus the selection criteria of SiC gate drivers will be addressed.

48 V Power Architecture

A newly emerging technology in the xEV vehicle world is that of 48 V dual-voltage architecture MHEV systems. In these vehicles, the primary voltage source is a 48 V Lithium Ion (Li-ion) battery pack. These 48 V battery packs are capable of driving much higher power loads, as compared to the 12 V battery. They are charged by the output of a permanent magnetic electric machine, called an Integrated Starter Generator (ISG) or Belt Starter Generator (BSG). The Starter/Generator functions as both the starter, and generator. It charges the battery and supplies current to the various 48 V vehicle loads. Starter/Generators come in various sizes, shapes, and power levels. They can be mounted at various locations along the powertrain, depicted as P0-P4, with the highest power rated types located on the vehicle’s transmission or rear axle.

Automotive 48V Systems Are Here Enabled by Semiconductor Solutions

As the need to reduce CO2 emissions becomes more critical in the fight to combat climate change, automotive electrification is becoming more mainstream. While there are many approaches to electrification, 48V mild hybrid systems are an “easy” path towards improving the fuel efficiency of traditional internal combustion engine (ICE) vehicles.

Also known as belt starter generators (BSG) and integrated starter generators (ISG), 48V systems enable stop/start functionality, but can also be used to boost acceleration, power vehicles electrically for short distances and support a range of 12V hydraulic/mechanical systems, such as power steering, that are migrating to 48V. In this presentation, onsemi will explore the rationale for electrification, review 48V mild hybrid system topologies, and introduce key semiconductor technologies that make these systems possible.

Vehicle Electrification

Vehicle Electrification will be a key technology to reduce carbon emission, increase vehicle efficiency, and reduce dependency on oil. By electrifying light vehicles, we can replace hydraulic or mechanical systems with electric systems; for example, hydraulic power steering with electric power steering, and mechanical or hydraulic pumps, such as a water pump, with an electric pump. Today this can be accomplished via numerous technologies, including start-stop (12 V & 48 V systems), Battery Electric (BEV), Hybrid-Electric (HEV), Plug-in Hybrid-Electric (PHEV), and Fuel Cell Electric Vehicle (FCEV). These new powertrain systems not only possess an increased number of power semiconductors, these semiconductors will operate at voltage levels between 12 and 400 V, withstanding a harsh automotive environment, in vehicles that will be part of a growing ride sharing, increased use, environment. onsemi has all the core technologies for vehicle electrification. Our power products and solutions offering includes IGBTs, high voltage gate drivers, high voltage rectifiers, super junction MOSFETs, high voltage DC-DC, as well as Wide Band Gap (WBG) developments in Silicon Carbide (SiC) and Gallium Nitride (GaN) for next generation solutions. Beyond silicon development, investments in advanced packaging include high power modules, single/dual sided cooled and dual sided direct cooled packages.

SiC Hybrid and Full SiC MOSFET Modules Improve Solar Inverter Efficiency and Power Density

The worldwide demand for solar inverters continues to snowball, driven both by the growth in renewable energy and the decreasing cost of electricity from solar farms. These solar farms use strings of solar panels rated at 1100 V or 1500 V. Using 1500 V reduces the overall installation cost per kilowatt compared with 1100 V systems but requires higher voltages on the boost and inverter circuits in the solar inverter. For reduced maintenance costs, solar farms generally use several smaller interchangeable inverters rather than one large central inverter. We will review how to increase the power density of 1100 V inverters by using full SiC boost modules. SiC hybrid modules configured in either symmetric boost or flying capacitor boost topologies increase the power density for 1500 V inverters. Finally, we will review the benefit of using SiC diodes in the output stages of 1100 V and 1500 V solar inverters.

SiC Solutions for Non Traction HV Applications

The increasing demand of efficiency and power density in any application inside a hybrid/electric car push in the direction to have innovative and more efficient power technologies. Wide-Gap semiconductor technologies are the solution to address the request to have low switching losses and high thermal behavior. In particular, SiC technology is now a reliable and performing alternative to reach high level of efficiency and performances not only in traction inverter, but in On Board Charging and DC-DC converter applications as well.

Silicon Carbide Solutions for Electric Vehicles

The widespread popularity of electric (BEV) and plug-in electric (PHEV) vehicles continues to grow at a rapid pace – an estimated 300k BEV sold in the U.S. in 2019, capturing roughly 2% of the total new car sales. On each one of these vehicles is an On-Board Charging (OBC) system that converts AC voltage from the grid to DC voltage to charge your battery. This webinar will explore how Silicon Carbide (SiC) enables these OBC systems to run more efficiently by reducing switching losses, minimizing the size and weight of the system, as well as providing an overall lower system cost.
