“…The circuit topology is a single-phase bidirectional half-bridge DC-AC converter, widely adopted in many power converter topologies [45][46][47][48]. In this experiment, the converter operates as an inverter connected to a 3 Ω resistive load, with a DC link voltage equal to 100 V.…”

Abstract:Residual lifetime estimation has gained a key point among the techniques that improve the reliability and the efficiency of power converters. The main cause of failures are the junction temperature cycles exhibited by switching devices during their normal operation; therefore, reliable power converter lifetime estimation requires the knowledge of the junction temperature time profile. Since on-line dynamic temperature measurements are extremely difficult, in this work an innovative real-time monitoring strategy is proposed, which is capable of estimating the junction temperature profile from the measurement of the dissipated powers through an accurate and compact thermal model of the whole power module. The equations of this model can be easily implemented inside a FPGA, exploiting the control architecture already present in modern power converters. Experimental results on an IGBT power module demonstrate the reliability of the proposed method.

“…The three major multilevel inverter topologies that have gained much research attention are diode clamped multilevel inverter [4,[13][14] , flying capacitor multilevel inverter [15][16][17] and cascaded H-bridge (CHB) multilevel inverter [3,5,8,11,[18][19]. Among the three topologies, cascaded H-bridge multilevel inverter is the most preferred because of its simplicity, reliability, modularity, minimum number of required components and the best fault tolerance [5,19]. The modular structure of the H-bridge inverter enables the inverter to be cascaded and stacked up for high power and voltage application.…”

“…The modular structure of the H-bridge inverter enables the inverter to be cascaded and stacked up for high power and voltage application. Additionally, the cascaded H-bridge inverter still can operate at low power levels despite failure generated from other cells [8,19]. However, the drawback of CHB inverter is it requires separate DC source for each module.…”

“…In order to track the PV maximum power point, several strategies have been proposed. The most diffused applications use the Perturb and Observe technique [5], where the setting of perturbation step can also be adaptive [6], and Incremental Conductance [7]. Several low level control algorithms have been proposed in tandem with such control strategies [8,9].…”

Abstract:In the context of grid connected photovoitaic (PV) generation systems, there are two paramount aspects regarding the Maximum Power Point Tracking (MPPT) of the photovoltaic units and the continuity of the service. The most diffused MPPT algorithms are based on either perturb and observe, or on an incremental conductance approach and need both PV current and voltage measurements. Several topology reconfigurable converters are also associated with the PV plants, guaranteeing fault-tolerant features. The generation continuity can also be assured by interleaved inverters, which keep the system operating at reduced maximum power in case of failure. In this paper, an evolution of a hysteresis based MPPT algorithm is presented, based on the measurement of only one voltage, together with a novel space vector modulation suitable for a two-channel three-phase grid connected interleaved inverter. The proposed MMPT algorithm and modulation technique are tested by means of several numerical analyses on a PV generation system of about 200 kW maximum power. The results testify the validity of the proposed strategies, showing good performance, even during a fault occurrence and in the presence of deep shading conditions.
