Summary This article presents an experimental evaluation of a three‐phase induction motor drive during pre‐fault and post‐fault operation. A three‐level boost converter is used at the front end of a two‐level voltage source inverter with a current control algorithm, and a predictive torque control is used for induction motor drive. This topology retains the normal operation under open‐circuit or short‐circuit of devices in any one of the inverter legs, and also the dc‐link voltage across the capacitors is balanced. The merits of the proposed scheme are highlighted and compared with existing fault‐tolerant converter topology (B4) using simulation and experimental results. Furthermore, simulation and experimental results of the proposed scheme in the field weakening region are presented to examine the drive operation above base speed.

“…(1) all parasitic components except for those specified in Figure 3a In order to make up for the drawbacks of the conventional boost converter, the interleaved and three-level boost converter have been developed and widely used for the hybrid hydrogen-fuel-cell railway system. These converters show low switching loss and can operate with higher switching frequency compared with the conventional boost converter [3,4,5]. In this paper, both interleaved and three-level boost converters thoroughly review for the high efficiency and power density through the analysis in various ways.…”

Step-up DC/DC converters are needed generally for the hydrogen-fuel-cell (HFC) hybrid railway system since the HFC has difficulty directly generating a high link voltage of over 1500 V for the high-power capacity inverter to drive the traction motor in the vehicle. These step-up DC/DC converters demand a high conversion efficiency with low weight and volume, due to the limited space in vehicle. In this paper, step-up DC/DC converters are presented and are evaluated for the HFC hybrid railway system. By choosing the interleaved boost converter and the 3-level boost converter as promising candidates, characteristics and features of both converters are presented through the analysis of the operational principles. In addition, the optimal design methods and results of boost inductor, output capacitor, and power semiconductor devices are presented based on theoretical analysis and a real design specification for the HFC hybrid railway system. Moreover, an optimal digital control design in terms of dynamic current response and reliability, such as current-balance or voltage-balance controls, is presented in this paper. In order to verify the analysis and design results, prototypes of both converters with the 600 V input and 1200 V/20 kW output specifications are constructed and the performance of the interleaved and 3-level boost converters are demonstrated through the experimental results. The experimental results show that the 3-level boost converter is more suitable for the HFC hybrid railway system in the sense of efficiency, power-density, and dynamic current response.

“…The high voltage semiconductor switches are required in such high power, high voltage applications, and this results in large losses in semiconductor switches. Therefore, research on three-level bidirectional converter (TLBC) is being actively carried out to lower the voltage stress of power semiconductors [4][5][6][7]. Figure 1 shows a TLBC circuit.…”

The voltage and current ripples in the three-level bi-directional converter (TLBC) can be reduced by an interleaving technique that controls a phase difference between the modules of power converter. On the other hand, the inductor current ripple in TLBC is increased due to the circulating current between the modules. In this paper, the effects of two interleaving methods on a two-phase TLBC, Z-type and N-type, are investigated and compared. In particular, capacitor current ripple, and voltage ripple are compared by two interleaving methods verified through Powersim (PSIM) simulation.
