In this study, we introduce a traction motor control unit developed to drive a series diesel hybrid electric truck. The electric drive of a heavy-duty vehicle requires a system configuration having a relatively higher voltage and larger current than in an light-duty vehicle. In addition, components having a high power density need to be developed in order to improve vehicle performance. For reducing...
Series hybrid electric vehicles (HEVs) have a power-train structure in which the engine, battery, generator, and traction motor are connected in series. As a result, the operational performance of HEVs depends on the performance of the traction machine. This paper proposes a traction torque control method for a series HEV application driven by an interior permanent-magnet synchronous machine (IPMSM)...
In this paper, the control performances of the three phase SVPWM inverter according to the phase current measuring method are compared. For this comparison, the current measuring methods using a current transducer (CT) and a shunt resistor are adopted. Furthermore, in the case of three shunt resistors are connected between under the emitter of power switch and the dc-link ground for phase current...
In this paper, the control performance of permanent magnet synchronous motor (PMSM) according to phase current sensing methods is analyzed. For this analysis, the current sensing methods using a current transducer (CT) and a shunt resistor are adopted. The strengths and weaknesses of the each method are analyzed, and the comparative study according to both methods is then performed. The detail analysis...
