Abstract-Availability is an important factor to be considered when designing wind turbine generator systems. The quest for increased availability is based on the following five design approaches -design for component reliability, active control for reliability, design for fault tolerance, prognostics, and design for maintainability. This paper reviews methods focussing on the first three, i.e. component reliability, active control, and fault tolerance. The paper further identifies some promising directions for further research.

“…The peak torque for a traction motor is limited by switching device temperatures. For an 11 kW PMSM motor, it is presented in [13] a drive control strategy that merge the active thermal management model with dynamic DC-link voltage adaptation. Thus, the switching losses can be decreased at low speed by decreasing the bus voltage resulting a considerable inverter losses decrease at low speed.…”

Power rectifiers from electrical traction systems, but not only, can be irreversibly damaged if the temperature of the semiconductor junction reaches high values to determine thermal runaway and melting. The paper proposes a mathematical model to calculate the junction and the case temperature in power diodes used in bridge rectifiers, which supplies an inductive-resistive load. The new thermal model may be used to investigate the thermal behavior of the power diodes in steady-state regime for various values of the tightening torque, direct current through the diode, airflow speed and load parameters (resistance and inductance). The obtained computed values were compared with 3D thermal simulation results and experimental tests. The calculated values are aligned with the simulation results and experimental data.

“…Only few active thermal control approaches have been proposed so far. Chosen control parameters are the switching frequency [2], [14], the modulation method [15], the dc link voltage [16], the gate voltage [17] or circulating reactive power [18]. As an example, a shortterm temperature drop can be prevented or reduced when losses are increased temporary by increasing the switching frequency.…”

Abstract-Thermal cycling is one of the main sources of aging and failures in power electronics. A possibility to reduce the stress to semiconductors is to control the amount of losses that occur in the device during operation. This work presents an active thermal controller that aims at reducing the junction temperature variations in the case of variable power profile. The switching frequency of the converter is the parameter that is affected by the active thermal control, while the operation of the converter remains unchanged. The novelty of the approach is that the switching frequency variation is exploited to prevent excessive cooling down of the semiconductor during a power reduction. A thermal model is used to estimate the losses, so the prior knowledge of the mission profile is not needed. The results of the proposed solution are validated with an experimental prototype and a wide-bandwidth temperature measurement system directly applied to the semiconductor chip. Finally, the impacts of the controller on the module's lifetime is estimated.
