Two New and Novel Cascaded Multilevel Inverters with Less Number of Components Utilizing Series Submultilevel Inverters

In this paper, two new cascaded inverters are proposed, by using the series connection of new Submultilevel inverters. Each of the proposed Submultilevel inverters consists of three batteries and eight power switches. Four algorithms are presented to determine the voltages of these batteries for each of the proposed structures. In this study the comparison between the proposed structures with c...

Combined Bidirectional Buck-Boost DC-DC Chopper-Mode Inverters With High-Frequency Link

Controlling Common-Mode Voltages in Multilevel Inverters

This paper proposes a novel method based on pulse width modulation techniques toreduce and control the common-mode voltage in three-phase multilevel inverters. Besides controllingthe common-mode voltage, this method is capable of controlling capacitors voltages and load currentswith low switching losses and harmonic contents. In fact, due to the existence of different pulsepatterns and the poss...

Power Frequency Inverters for High Voltage Tests

The essential demand in high AC voltage testing is the availability of a test voltage with high quality, which is variable in amplitude and frequency. The power supply should not have any influence on the measurements – even the PDmeasurement and should be able to control a fault of the test objects insulation safely. These demands can be fulfilled using modern IGBT inverters. Two level voltage...
