Power converters have widespread applications in automotive, renewables, and power systems. The demand for power modules with low power consumption and high efficiency has increased due to advancements in semiconductor devices. So, power converters need to be highly efficient to reduce costs associated with energy dissipation and cooling requirements. This paper discusses various active thermal control methods for high-power power converters. It covers modulation and configuration techniques, ranging from single configurations to cascaded, modular, and multilevel converters. These concepts form the basis of power electronics building blocks, particularly relevant in all-electric ship systems. Power electronics building blocks represent a This article has been accepted for publication in IEEE Access.

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 analysis of this example shows in principle, that it is possible, to increase the lifetime and therefore the reliability of the IGBT-module by increasing the power losses during low load conditions in order to reduce the junction temperature swing [11], [12], [13], [14]. Besides the control strategy, it is important to find a suitable control variable to influence the junction temperature over a wide range.…”

Load changes of electrical machines driven by inverters cause temperature swings of the semiconductor devices in IGBT modules of the inverters. These temperature swings lead to mechanical strain in the different material layers of the IGBTpower-modules and limit the numbers of cycles to failure and therefore reduce the lifetime of the IGBTs. This paper presents a temperature control system which is paralleled to the standard torque control system. It aims to reduce the magnitude of temperature swings of the semiconductor devices of IGBT modules caused by load changes of an interior permanent magnet synchronous machine. The principle method is, to increase the temperature of the semiconductor devices of the IGBTmodules by creating higher power losses during low load conditions of the machine without affecting torque and speed. This reduces the magnitude of the load induced temperature swings of the semiconductor devices of IGBT-modules and increases its lifetime at the cost of increased power losses. Three variables have been identified that influence the power losses in inverter modules without necessarily affecting the output power of the permanent synchronous machine. These variables are switching frequency of the inverter, length of the clamping area when a discontinuous modulation is applied and the reactive component of the inverter current. The influence of each variable which regards to the losses in the IGBT-power-modules is explained and the related control methodology is described. As the influence on each of the three variables has its advantages and disadvantages, the proposed temperature control system is designed to influence all three variables concurrently for most effective reduction of the magnitude of temperature swings in the IGBT. While the proposed temperature control system is described in this paper for a two-level threephase inverter feeding an interior permanent synchronous machine, its principle may be applied to other converter topologies. The analytic results have been verified by experimental results obtained from a test set up with a 1200 V/300 A three-phase inverter supplying a 70 kW interior permanent magnet synchronous machine coupled to a 30 kW asynchronous load machine.
