Technology Architecture of Traction Inverter for EV
Traction Inverter Solutions
- The responsiveness of the inverter and the electric motor it controls correlate directly to the “feel” of the vehicle and consumer satisfaction. Power levels from 10 kW to 450 kW, and these systems require extremely robust IGBT and silicon carbide (SiC) components.
- 96-volt to 1000-volt batteries supply power to traction inverters, requiring inverter components to be rated from 120 volts to 1200 volts while operating at current levels up to 850 A per phase.
- A full ecosystem of parts to support wide bandgap power designs, including SiC diodes, SiC MOSFETs, and SiC Modules.
- MOSFET for Traction Automotive
- IGBT for traction Automotive
- SiC Modules for Traction Automotive
- Sinusoidal Pulse width Modulation (SPWM), Space Vector Pulse width modulation (SVPWM) control technique developed as per the application of inverter.
- Field Oriented Control (FOC) Algorithms:
- flux weakening for wider speed operation of traction drive.
- PI control with anti-windup, torque mode and speed mode.
- Space vector modulation.
- Provides the plant based MBD as per the customer Requirement.
DC-DC Converter
A type of power converter known as a DC-DC converter changes the voltage level of a DC source. It can be either unidirectional, which only sends power in one way, or bidirectional, which can do both. A DC-DC converter is also an essential part of a Battery EV's architecture since it is needed to switch power from a high voltage (HV) bus to a 12V low voltage (LV) bus so that the LV battery can be charged, and the onboard electric devices can be powered.
Components of A DC-DC Converter
