One of the critical aspects of electric vehicle (EV) inverter design and engineering is the seamless integration of the inverter with the electric motors. The inverter plays a pivotal role in controlling the speed and torque of the electric motor by regulating the frequency and amplitude of the electrical energy supplied to it.
The electric vehicle inverter is a fundamental component in the EV powertrain system, acting as the interface between the battery and the electric motor. Its primary role is to manage the electrical energy flow, ensuring that the motor receives the appropriate voltage and frequency to operate efficiently.
One of the fundamental components of electric vehicle (EV) inverters is the semiconductor devices, which play a crucial role in the conversion of direct current (DC) to alternating current (AC).
This article presents a comprehensive review of modern traction inverter systems, their possible control strategies, and various modulation techniques deployed in electric vehicles (EVs). The traction inverter is a fundamental component in electrifying the EV drive system due to its critical functioning in a wide range of operations.
