This paper introduces a new topology of multilevel inverter, which is able to operate at high performance. This proposed circuit achieves requirements of reduced number of switches, gate-drive circuits, and high design flexibility. In most cases fifteen-level inverters need at least twelve switches. The proposed topology has only ten switches. The inverter has a quasi-sine output voltage, which is formed by level generator and polarity changer to produce the desired voltage and current waveforms. The detailed operation of the proposed inverter is explained. The theoretical analysis and design procedure are given. Simulation results are presented to confirm the analytical approach of the proposed circuit. A 15-level and 31-level multilevel inverters were designed and tested at 50 Hz.

<p>This paper presents a novel topology of Single-phase multilevel inverter for low and high power applications. It consists of polarity (Level) generation circuit and H Bridge to generate both positive and negative polarities. The proposed topology can produce more output voltage levels by switching dc voltage sources in series and parallel. The proposed topology utilizes minimum number of power electronic devices which leads to the reduction of cost, size, and weight low and consumes low power which improves the efficiency. Switching pulses are generated using Phase disposition (PD) pulse width modulation technique. Finally the effectiveness of the proposed topology is verified using MATLAB/SIMULINK software tool. 7level asymmetrical multilevel inverter prototype hardware is prepared to support the proposed topology to verify the effectiveness and its validity.</p>

Multilevel Inverters

In this paper, a new basic 15-level inverter is proposed. By developing the proposed basic unit, a 71-level inverter and generally an [Formula: see text]-level inverter are proposed. Then, the proposed multilevel inverter is compared with several conventional multilevel inverters in design of minimum 15 levels and 71 levels at the output. By comparing these inverters, it is obtained that the proposed inverter is able to generate higher number of output levels by using lower number of DC voltage sources and power electronic devices that lead to decreased complexity, installation space and total cost of the inverter. Finally, the correct performance of the proposed inverter is reconfirmed through the simulation and experimental results of a 15-level inverter.

With the development of China’s electric power, power electronics devices such as insulated-gate bipolar transistors (IGBTs) have been widely used in the field of high voltages and large currents. However, the currents in these power electronic devices are transient. For example, the uneven currents and internal chip currents overshoot, which may occur when turning on and off, and could have a great impact on the device. In order to study the reliability of these power electronics devices, this paper proposes a miniature printed circuit board (PCB) Rogowski coil that measures the current of these power electronics devices without changing their internal structures, which provides a reference for the subsequent reliability of their designs.
