ELECTRIC TRUCK TRACTION INVERTER Russian patent published in 2024 - IPC B60L15/20 

FIELD: vehicles.

SUBSTANCE: invention relates to electric truck traction inverter. Inverter comprises a housing, an electromagnetic compatibility filter, a DC bus capacitor, power SiC-transistor modules, power module temperature sensor, control board with processors, current sensors, power module drivers, backup power supply. Electromagnetic compatibility filter is connected to the DC bus capacitor and is connected to power SiC-transistor modules, one of which is equipped with a temperature sensor. Modules are connected to each other and to the control board. Processor is made with possibility of data exchange with program of upper level of electric truck control system. Processor receives from the auxiliary coprocessor data from the rotor position sensor of the electric motor relative to the stator. Traction inverter comprises two current sensors. Current sensors consist of a ferromagnetic ring and a Hall sensor.

EFFECT: reduced weight and size of the inverter.
