Asymmetric Phase-Shift Modulation Strategy of DAB Converters for Improved Light-Load Efficiency
IEEE transactions on power electronics, 2022Dual active converter (DAB) can achieve high efficiency when the voltage ratio (the ratio of the input voltage to the output voltage equivalent to the primary side) is one, but when the voltage ratio is not one, the light-load efficiency drops sharply ...

Electrolytic capacitorless Vienna rectifiers have many advantages, such as longer lifetime and higher power density. However, the reduced dc-link capacitance aggravates the voltage stress due to the neutral point (NP) fluctuation.

With the loss of a large number of space vectors under switch open-circuit faults, the neutral point potential (NPP) control of T-type three-level converters is faced with a huge challenge. It becomes harsh to balance the NPP and maintain the symmetry of

Pulsewidth Modulation Strategies
IEEE Industrial Electronics Magazine, 2011This article reviews the nonsinusoidal CPWM and SVPWM techniques and deals with the three possibilities of calculation of pulsewidths after the addition of a zero-sequence signal. A general algorithm is proposed and adapted for dealing with the control of the three-level NPC inverter and also the Z-source converter. Experimental results corroborate the

Hybrid SVPWM Modulation Strategy for Auxiliary Resonant Commutated Pole Inverter
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2021Although the auxiliary resonant commutated pole inverter (ARCPI) can achieve soft-switching for main switches, the auxiliary commutation circuit (ACC) itself has a loss, especially under high frequency.

Implementation of Pulsewidth Modulated Inverter Modulation Strategies
IEEE Transactions on Industry Applications, 1982A description is given of a number of new circuit techniques, useful primarily in the control hardware of inverter drives using ``sub-harmonic''- or ``triangulation''-based pulsewidth modulation algorithms. Most aspects of such a system are covered. These include generation of the ``reference'' and ``carrier'' waveforms, carrier merging (including an ...

The switching frequency of high-power medium-voltage three-level inverters is relatively low due to the limitation of switching loss. Thus, the output performance of the inverter will be deteriorated if the fundamental frequency is increased (in other ...
