Abstract:

Purpose. Development of design concept of control approach for the inverter for simultaneous control of the energy flows from two DC sources in electric vehicle drivetrain.

Methodology. Methods of mathematical modeling and simulation were used while researching modes of AC and DC components using one inverter. Also, a comparative analysis method was applied to select the optimal method for implementing the control algorithm.

Findings. Working efficiency of a two-way feed scheme for supplying asynchronous motor from two DC sources is shown. The work suggests the scheme design concept, provides a transistor control algorithm, and describes physical processes and engine characteristics.

Originality. Connection of DC source to a common (zero) point of the AC electric motor when the latter is fed from the three-phase frequency converter, allows transmitting the energy to the motor without the dedicated converter. Special valve switching algorithm for separate control of power flows is suggested.

Practical value. The new scheme is a prerequisite for solving tasks of combining several electric power sources controlled by single combined converter, which simplifies the electric drivetrain in hybrid and electric vehicles.
