High voltage systems, typically defined as electrical systems operating at voltages above 1,000 volts for alternating current and 1,500 volts for direct current, are integral to modern power generation and transmission. These systems play a crucial role in ensuring efficient electricity distribution over long distances.
In the case of an EV HV inverter, the definition of the safe state is quite complex due to a high amount of energy flowing into the electrical motor. In some cases this can result in unstable behavior instead of ensuring the safe state that is requested by the system.
In the example of an HV inverter for EVs, the functional assumption could be resumed as follows: an inverter is the main traction system of an electric vehicle. It controls energy conversion between an electric source (HV DC battery) and the mechanical shaft of the electric motor, based on torque requested from the vehicle control unit (VCU).
The two-level inverter is the most common power converter used in electrified vehicles and in the industry, with the power range of tens of kilowatts up to hundreds of kilowatts.
Weight and power density – The wide band-gap switch and powertrain integration are the key technologies enabling high-power density inverter design. The inverter power density target of OEMs continues to, for example, 100 kW/L in the US market by 2025. The use of SiC enables 800-V DC bus voltage, reduce the current rating and wiring harness.
When electrical current travels through conductors, resistance produces heat, leading to power dissipation. By increasing the voltage and reducing the current, high voltage systems mitigate these losses, thereby enhancing overall system reliability and efficiency.
