Active decoupling methods are developed for tackling the inherent second-order ripple power. However, in all the active decoupling methods developed for single-phase current source rectifier (SCSR), the dc output voltage is limited to half the peak amplitude of the ac source voltage. That limits SCSR's wide applications. Addressing that issue this study proposes a family of two-port switching networks...
To improve the input and output waveform quality in terms of total harmonic distortion (THD) for the three-level diode-clamped matrix converter topology, the phase disposition carrier-based modulation method is a good option. However, it is difficult to implement because of the loss of zero-current commutations. Aiming at addressing the problem above, a hybrid switching sequence for the phase disposition...
A selective harmonic elimination (SHE) inverter can eliminate beforehand-appoint harmonic by calculating the equations set, therefore it can eliminate harmonic effectively in theory. The connection and break of switching devices all need a little time, thus the narrow pulse of the ideal output voltage waveform is difficult to realize. For obtaining practical output voltage waveform, optimization strategies...
