Space Vector Modulation Based on Classification Method in Three-Phase Multi-Level Voltage Source Inverters
Pulse Width Modulation (PWM) techniques are commonly used to control the output voltage and current of DC to AC converters. Space Vector Modulation (SVM), of all PWM methods, has attracted attention because of its simplicity and desired properties in digital control of Three-Phase inverters. The main drawback of this PWM technique is 
its complex and time-consuming computations in real-time ...

متن کاملDesign of Multi Threshold (Multi Vth) Level Converters for Block Interfaces
High-performance and low-power are the two main criteria in modern digital design. Level converters are important to transfer low voltage input swing signal among the circuits operating at different voltages to get high voltage output swing signal. Previously feedback level converters suffer from short circuit power and long propagation delay. Multi Vth level converters and multiple supply volt...
متن کاملA Modified Phase-Shifted Pulse Width Modulation to Extend Linear Operation of Hybrid Modular Multi-level Converter
Recently, hybrid modular multi-level converters, which are configured as full and half bridge sub-modules, are developed and utilized in the wide area of applications. Compared to its non-hybrid counterpart, these converters have several advantages such as the ability to nullify the DC side fault current and controlling AC side reactive power during the faults. This paper proposes a modified ph...
متن کاملDC Voltage Control and Power-Sharing of Multi-Terminal DC Grids Based on Optimal DC Power Flow and Flexible Voltage Droop Strategy
This paper develops an effective control framework for DC voltage control and power-sharing of multi-terminal DC (MTDC) grids based on an optimal power flow (OPF) procedure and the voltage-droop control. In the proposed approach, an OPF algorithm is executed at the secondary level to find optimal reference of DC voltages and active powers of all voltage-regulating converters. Then, the voltage ...
متن کاملA Universal Voltage Level Converter for Multi-VDD Based Low-Power Nano-CMOS Systems-on-Chips (SoCs)
Level Converters are key components of multi-voltage based systems-on-chips. Recently, a great deal of research has been focused on power dissipation reduction using various types of level converters in multi-voltage systems. These level converters include either level up conversion or level down conversion. In this paper we propose a unique level converter called universal level converter (ULC...
