This paper presents and analyzes a non-dissipative balancing system for supercapacitors. The circuit design is carried out by means of a controlled buck-boost converter in order to have the same voltage in each supercapacitor. The paper presents an energy loss analysis in two cases: a dissipative and a non-dissipative balancing circuit. It also develops a(More)
This paper analyzes the benefits and drawbacks of using a modified center-tab rectifier in a high-current bidirectional dc-dc converter. In order to do this, an analytical model of the rectifier is proposed, and a design procedure based on this model is presented. Simulations and experimental data from a prototype validate this model. This topology is also(More)
This paper analyzes the benefits and drawbacks of using a modified center-tab rectifier in a high current bidirectional DC-DC converter. This topology is also optimized in order to reduce diode/switch reverse voltage stress. One side of the converter has to transfer currents up to 100A, so the main reason for choosing this topology is the lower conduction(More)
Salicylic acid (SA) is an essential hormone for plant defence and development. SA perception is usually measured by counting the number of pathogens that grow in planta upon an exogenous application of the hormone. A biological SA perception model based on plant fresh weight reduction caused by disease resistance in Arabidopsis thaliana is proposed. This(More)
