The most stressful operation point for the inverter of an electric vehicle drive is at low speed. In this operation point, one power semiconductor is mainly stressed because of a high loss concentration. The possibilities of distributing the losses among the power semiconductors through a new modulation is studied for the three-level NPC and the T-Type inverter. The effect of the proposed modulation...
This paper presents a method for the calculation of the power semiconductor rating based on data sheet parameters of the three-level Neutral-Point-Clamped (NPC) inverter. Beside the basic equations for calculating the turn-on and turn-off losses for Insulated Gate Bipolar Transistors (IGBT) and diodes, the electrical inverter topology, the different current paths for the commutations and the critical...
A comparison of the two-level voltage-source inverter, the three-level Neutral-Point-Clamped inverter and the T-Type inverter based on the power semiconductor rating is presented for drive inverters of electric vehicles. The comparison of the power semiconductor design rating is done for four different drive train configurations: normal operation with a constant DC-link voltage, an overload capability,...
Small wind turbines are used for local energy production or in island networks. They are usually installed at places, where the wind speed is relatively low and considerable fluctuation occurs, resulting in a challenge to offer a high energy production especially at low and gusty wind speeds. For these conditions an optimal drive train has to be selected. In this paper the focus is on typical rectifier...
