The aim of this paper is to study the influence of the drive train topology on the temperature of the different components in permanent magnet synchronous motor (PMSM) drives applied to electric/hybrid vehicles. The temperature is a critical parameter because it is directly related to the lifetime and reliability of a device. This is particular important for PMSMs since it also influences the magnetic...
Stand-alone power systems are a challenging option to supply remote equipments in many applications. They include renewable energy generators whose intermittent power supply requires an appropriate energy storage component to balance the power mismatch between the generation and the demand. Batteries are the obvious choice for this purpose. However, the irregular fluctuations and hard transients would...
This paper presents a variable speed ac drive based on a permanent magnet synchronous motor, supplied by a three-phase fault-tolerant power converter. In order to achieve this, beyond the main routines, the control system integrates a reliable and simple algorithm for real-time diagnostics of inverter open-circuit faults. This algorithm performs an important role since it is able to detect an inverter...
Since standalone power systems with renewable energy generators are becoming competitive with respect to a grid connection solution for supplying telecommunications equipments in remote areas, power electronics converters are facing new challenges to simultaneously match the parameters of the renewable energies and to fulfil the telecommunications strict requirements. This paper presents a variety...
