A single-phase four-switch rectifier with considerably reduced capacitance is investigated in this paper.The rectifier consists of one conventional rectification leg and one neutral leg linked with two capacitors that split the DC bus. The ripple energy in the rectifier is diverted into the lower split capacitor so that the voltage across the upper split capacitor, designed to be the DC output voltage, has very small ripples. The voltage across the lower capacitor is designed to have large ripples on purpose so that the total capacitance needed is significantly reduced and highly reliable film capacitors, instead of electrolytic capacitors, can be used. At the same time, the rectification leg is controlled independently from the neutral leg to regulate the input current to achieve unity power factor and also to maintain the DCbus voltage. Experimental results are presented to validate the performance of the proposed strategy.

“…Separated and/or combined effects of such constraints can have serious consequences on different parts of the component and cause its failure. According to previous work [16], [17] it was noted that most of the encountered failure mode of MPF capacitors during their lifetime can be monitored by ESR and C evolution.…”

Supercapacitors (SCs)impedance modeling represents one important key to get information for SCs health monitoring and simulation. As a matter of fact, SCs behavior is dependent on various parameters such as pore size distribution of electrodes, electrolyte state, temperature, aging… We propose in this work to model supercapacitor taking into account physical considerations. Basing on theory on homogenous structure impedance, we define in first time, single pore (SP) model using uniform size of pores distribution. In the second step, we attempt to generalize this circuit model considering an electrode with different pores sizes or different penetrabilities of the pores. This model called multi-pore (MP) model (or multi-penetrability model) has been developed by our laboratories. This model allows analyzing the behavior of supercapacitor by modelling each group of electrode pores as a branch of an electrical equivalent circuit. This paper is the first in literature to give a simple and reproducible method for MP model parameters identification. The validity of the identification method will also be verified at different supercapacitor aging rates thanks to experimental aging tests.
