Kus, V.; Josefova, T. Applied Electronics (AE), 2014 International Conference on, 2014
This paper presents an effect of dead times on values of an input current harmonics drawn from an electric grid by a voltage-source active rectifier. The first part shows a derivation of the effect on one pulse of the voltage and then the values of the current harmonics are derived. The main section discusses a description of voltage with the ...

The use of an active voltage clamp in insulated DC/DC converters allows a limitation of the voltage stress due to transformer leakage inductance, a reduction of the commutation losses, and an increase of the switching frequency. It is therefore important to ensure soft switching in the whole operating range; the penalty is a considerable worsening of converter efficiency and electromagnetic ...
Griva, G.; Oleschuk, V. Industrial Electronics, 2009. IECON '09. 35th Annual Conference of IEEE, 2009
New method of synchronized pulsewidth modulation (PWM) has been disseminated for control of dual neutral-point-clamped inverters feeding asymmetrical dual three-phase (six-phase) motor drive with two DC voltage sources. A novel control strategy for this drive topology is based on variation of switching frequencies of each inverter depending on the magnitudes of voltages of the corresponding DC sources. Specialized control scheme ...
Lascu, C.; Trzynadlowski, A.M.; Kirlin, R.L. Applied Power Electronics Conference and Exposition (APEC), 2010 Twenty-Fifth Annual IEEE, 2010
Operation of switch-mode converters results in electromagnetic noise propagating throughout the power electronic system. PWM strategies with fixed switching frequency generate harmonics in the spectra of converter voltages and currents. Random pulse width modulation techniques allow elimination of the harmonics, resulting in a continuous spectrum of noise, that is, a spectrum retaining all frequency components. As a next step in ...

The fundamental operational parameter that controls the losses in series resonant power converters was found to be the (reflected) voltage transfer ratio. Losses, which are a function of the average current (such as conduction losses of IGBTs and diodes), are independent of the switching frequency. Losses which are associated with the RMS are a function of both the (reflected) DC ...
