“…However, the amount of power that can be transferred is limited by the size of the coupled inductor or high-frequency transformer [21]. A recent development in DC-DC converters has shown that a multilevel inverter structure such as a T-type inverter that can offer higher efficiency as compared to the NPC inverter due to lower conduction and switching power losses can be adopted [22][23][24]. In fact, T-type inverter topology has been exploited for several DC-DC applications that require high energy efficiency.…”

This paper presents the design and analysis of a three-level hybrid boost converter based on a single-phase threelevel T-type inverter. The proposed converter can provide high energy conversion efficiency and high voltage gain capability with reduced component count. The pulse-width-modulation signals of the proposed converter are generated by comparing two duty cycles and two triangular carrier signals. The proposed converter consists of four power switches, four diodes, an inductor, and two capacitors. Detailed converter operations at each switching state with the corresponding voltage and current waveforms of each component are discussed. The functionality and performance of the proposed converter are verified through simulation and experimental results.

“…But as the full-bridge configuration is not used, this topology is not suitable as a single unit which will generate only a three-level output for a Module Integrated Converter (MIC). In [49], a similar half-bridge configuration for a T-type inverter is used for electric vehicle application. The work results in only a three-level output for a bidirectional converter configuration.…”

The Multilevel inverters (MLIs) are a new breed of power electronics converters. They are primarily used for the conversion of dc power to ac power. The two-level inverters are conventionally used to obtain ac power, but it requires operating the switches under very high switching frequency. Besides, the two-level inverter necessitates the use of LC filters with the switches operating under high dv/dt stress. The MLIs offer the advantage of utilizing several dc voltage sources to generate a stepped ac waveform with the proper arrangement of switches. Investigation of a Transistor Clamped T Type H-Bridge Multilevel Inverter (TC-TT-HB-MLI) with Inverted Double Reference Single Carrier PWM Technique (IDRSCPWM) for Renewable Energy Applications are discussed in this paper. A PV source is taken as an input to the TC-TT-HB-MLI. For different modulation indices like 0.85, 1 and 1.25, the FFT analysis is performed and presented, which corresponds to the variations in the irradiations from solar energy. A single unit of the TC-TT-HB-MLI is extended to a generalized MLI structure named Generalized Transistor Clamped T-Type H-Bridge Multilevel Inverter (GTC-TT-HB-MLI). The significant benefits of GTC-TT-HB-MLI are the multiple numbers of reductions in the switch count, and driver circuit counts for a higher number of MLI levels. Fast Fourier Transform (FFT) analysis is carried out on the MLI output to calculate the total harmonics distortion (THD). The experimental verification is performed using SPARTAN 3E-XCS250E; the gate signals are generated and provided to the switches.

Utilisation of more than one energy source in the electric vehicle (EV) ensures the reliable riding of the vehicle without range anxieties. Solar PV, battery and ultra-capacitor are viable sources to power the EV. A novel dual input-dual output dc-dc converter is proposed for the integration of the above sources for the EV application. The converter can be used to transfer power between the input sources and loads/utility grid/other EVs. The proposed converter can be operated in ten different modes using the same structure by controlling the appropriate switches. The equivalent circuits with the analytical waveforms of significant modes of operation of the converter are discussed in this study. The output equations of all ten modes are derived. The theoretical analysis of the converter is verified experimentally using a 1 kW laboratory prototype and the observed experimental results are shown in the study. A strategy for selecting a mode according to the status of the vehicle, grid, battery etc. is developed. The loss breakdown analysis and efficiency profile of the converter are presented. Finally, the performance comparisons of the proposed converter with the reported converters are carried out in terms of component counts, a number of operating modes etc.
