Driving the electrification of heavy-duty vehicles
Currently, the development of electric buses for urban transportation is accelerating and both, smaller delivery vehicles and long-range trucks are following. The all-electric heavy-duty vehicle demands highly efficient semiconductor solutions in a range from some watts to several hundred kilowatts, spanning at least 5 decades of power.
Inside the vehicle, two parallel worlds of electronics coexist. One is the low-voltage domain supplying on-board functions from driver convenience to lighting in a 12 V or 24 V environment. High-voltage batteries, topping off at close to 1000 V, drive the other world. The largest consumer of power remains the drive train, followed by climate control systems for heating and air conditioning. Subsystems that include pumps, fans and compressors are omnipresent and require highly efficient semiconductor solutions. The link between those worlds are DC-DC-converters that replace the classical alternator, which is now obsolete.
Besides driving an electric vehicle, charging the batteries is an important topic. Several potential options for this exist. On-board chargers connected to three-phase supplies pose a potential solution if longer periods for charging are available. Opportunity charging to supply power on dedicated positions is a further option. Either wireless power transfer by inductive coupling is used or an electrical connection is established by pantograph. Charging the vehicle with high-power DC-chargers is the most powerful option. This currently allows charging powers of up to 350 kW. Operation with two chargers in parallel can even double the charging power.

Podcast4Engineers #1: Electric vehicle charging on the rise
The first episode of our new podcast series introduces you to the topic of charging electric vehicles: In particular, what scenarios are available for charging, what does this mean for the respective topologies and how can designers deal with it? Our expert has all the answers and gives you an exciting insight into the beginnings of electric mobility.
High ruggedness against vibration and shock
The reliability of power semiconductors used in CAV applications must meet the stringent requirements of the traction market but at the lower costs and high power density associated with the automotive market. The rugged construction of the PrimePACK™ modules and its high level of thermal and power cycling capability make it especially suited for heavy and dynamic mission or load cycles. Choose for example 1200 V PrimePACK™ 2.
Power modules for auxiliary drives
Infineon’s unique 1200 V CoolSiC™ MOSFET adds advantages that are key for the demands of all-electric heavy-duty vehicles in the fields of auxiliary drives like air condition or convenient systems. Superior gate oxide reliability enabled by state-of-the-art trench design, best in class switching and conduction losses, highest transconductance level (gain), threshold voltage of Vth = 4 V and short-circuit robustness. In Easy 1B and 2B housing they offer a very good thermal interface, a low stray inductance and robust design as well as PressFIT connections. Choose 1200 V CoolSiC™ MOSFET modules in half-bridge, four-pack or six-pack configuration.
