This paper presents a model-based method to increase the dynamics of a current control loop within field-oriented control. The improvement is achieved by compensating for time delays within the control loop. The presented method is verified both through simulations using MATLAB/Simulink and with measurements using a rapid-control prototyping platform.
This paper describes the main components of an electric drive in a novel electric cargo tricycle. The main components are a Mosfet inverter, an axial flux synchronous machine, and a Li-Ion battery package. The most important specifications and functions of the tricycle and the electric drive are explained. Particular focus is laid on the inverter design and the experimental setup that was used for...
In order to increase the efficiency of a PMSM drive for an electric vehicle an inverter with low conduction and switching losses is required. Further an inverter with less voltage harmonics reduces the iron losses in the PMSM. To achieve these requirements the paper proposes a three-level MOSFET inverter with active neutral point clamping and soft switching at turn-on. The resonant circuit for soft...
