There is the second harmonic current at the output DC side of the single-phase rectifier for the instantaneous input power pulsation at twice the AC frequency. This second harmonic current will be detrimental to its output utilities without a large capacitor at the DC-link. In this paper, the advantages and disadvantages were analyzed through the comparisons of two waveform control algorithms of voltage...
The DC current of the single-phase inverter or rectifier contains low frequency ripple whose frequency is twice that of the AC voltage. Traditionally, electrolytic capacitor is used to eliminate these ripple, but it has relatively short lifespan and affect the lifetime of the entire inverter or rectifier system. In this paper, a single-phase bidirectional bridge topology without electrolytic capacitor...
Fuel-cell power systems comprising single-phase dc/ac inverters draw low-frequency ac ripple currents at twice the output frequency from the fuel cell. Such a 100/120 Hz ripple current may create instability in the fuel-cell system, lower its efficiency, and shorten the lifetime of a fuel cell stack. This paper presents a waveform control method that can mitigate such a low-frequency ripple current...
Fuel-cell power systems comprising single-phase DC/AC inverters draw low-frequency AC ripple currents at twice the output frequency from the fuel cell. Such a 100/120 Hz ripple current may create instability in the fuel cell system, lowers its efficiency, and shortens the lifetime of fuel cell stack. This paper1 presents a waveform control method that can mitigate such a low-frequency ripple current...
