The model predictive control (MPC) predicts all the possible behaviors and selects an optimal switching state which minimizes the predefined cost function at the next step, and is emerging as a powerful control method in power electronics. However, for a single phase T-NPC inverter with the conventional MPC method, only three different voltage vectors can be generated, which significantly impairs...
Wide bandgap (WBG) semiconductor devices allow power electronic converters to achieve higher efficiency, higher power density and potentially higher reliability. However, the design challenges accompanied by applying the new WBG devices have risen accordingly. In this paper, a non-isolated bidirectional DC-DC converter equipped with Gallium Nitride (GaN) semiconductor transistors is presented. The...
Direct bypass of DC-DC boost converter in traction inverter has many advantages including increased efficiency and pass-through capability. This paper explains different practical aspects of direct bypass of the boost stage of traction inverter using diode. Bypass diode enters into the linear operating region (DC Q-point) when the battery discharges through the bypass diode to drive the electric motors...
