A novel modified space vector pulse width modulation (MSVPWM) strategy for Z-Source inverter is presented. By rearranging the position of shoot-through states, the frequency of inductor current ripple is kept constant. Compared with existing MSVPWM strategies, the proposed approach can reduce the maximum inductor current ripple. So the volume of Z-source network inductor can be designed smaller...

This paper introduces hexagonal shape sensors that is a meander and mesh type. Modelling, simulation and development of Hexagonal Sensor and the results are discussed in this paper. The characteristics of hexagonal spiral inductor and interdigital capacitor are determined. The hexagonal spiral inductor is a new electronic sensor that can be used for various measurements that produces magnetic f...

Regenerative braking is presented in many electric traction applications such as electric and hybrid vehicles, lifts and railway. The regenerated energy can be stored for future use, increasing the efficiency of the system. This paper outlines the benefits of the MMC (modular multilevel converter) in front of the cascaded or series connection of converters to achieve high voltage from low volta...

High pressure inductively coupled plasma (ICP) sources are used in numerous applications, in particular for the testing of thermal protection materials used to protect space (re-)entry vehicles. The planetary gas is injected in a swirling, annular way into a heat-resistant quartz tube, surrounded by an inductor. A radio-frequency electric current runs through the inductor and induces a secondar...

A new radio frequency (rf) linear accelerator (LINAC) system with high efficiency has been developed by AIBT. The general designs of such a rf LINAC system are briefly discussed. This system includes a plurality of resonators each including an inductor circuit that is connected to at least two rf electrodes. Detailed designs of a system where two of the adjacent rf electrodes are connected to t...

Because the on-board charger (OBC) is installed in electric vehicles (EVs), high power density is regarded as a key technology. Among components of the OBC, inductors occupy more than 30% of the total volume. Thus, it is important to reduce the volume and the weight of inductors while maintaining thermal stability. Discontinuous conduction mode (DCM) can satisfy these requirements; however, onl...

Electric drives are gaining much importance in the present scenario, as the conventional energy sources are at the verge of depletion. The PMDC (Permanent Magnet Direct Current) Motor Drives are becoming popular, for its usage in compact electric vehicles. This paper presents a comparative study of well-known KY converter, its coupled inductor step-up derivative, with the boost converter to acc...

A novel bidirectional DC-DC converter is presented in this paper. The circuit configuration of the proposed converter is very simple. The proposed converter employs a coupled inductor with same winding turns in the primary and secondary sides. In step-up mode, the primary and secondary windings of the coupled inductor are operated in parallel-charge and series-discharge to achieve high step-up ...
