The model based temperature control system examined in this paper increases the expected lifetime of IGBT power modules by decreasing the magnitude of temperature swings occurring during operation. In order to achieve this goal additional power losses are produced during low load conditions. This is carried out by presetting a reactive current. The three level neutral point diode clamped three phase...
Interleaved switching of parallel inverters has previously been proposed for efficiency/size improvements of grid connected three-phase inverters. This paper proposes a novel interleaving method which practically eliminates insulated gate bipolar transistor (IGBT) turn-on losses and drastically reduces diode reverse recovery losses. The reduction in switching losses are obtained by interleaving two...
In the last decades, the interest in solar photovoltaic (PV) energy has increased considerable around the world.

A Reverse Conducting IGBT (RC-IGBT) is a promising device to reduce a size and cost of the power module thanks to the integration of IGBT and FWD into a single chip. However, it is difficult to achieve well-balanced performance between IGBT and FWD. Indeed, the total inverter loss of the conventional RC-IGBT was not so small as the individual IGBT and FWD pair. To minimize the loss, the most important...
