This paper proposes a new energy loss observer for batteries that has a good accuracy and low complexity. This observer can provide a support for battery management systems (BMS) in terms of predicting battery energy loss and/or battery internal temperature for given load profiles, and this enhances BMS capabilities for predictive and corrective actions. The typical observer requires an accurate battery...
In this paper, a multipurpose model of a proton exchange membrane fuel cell for household appliances is proposed. According to a conventional mathematical approach, the proposed model is derived from the physical and electro-chemical equations that rule the fuel cell behaviour. Differently from existing models, a parametric analysis is carried out and a few tunable parameters are accurately selected...
This paper introduces an electro-thermal model of an inverter implemented in PLECS. This model is able to calculate IGBT junction temperature with a mission profile. Look up tables (LUT) of switching power loss are generated by running physics-based IGBT and diode models under different operating conditions. The inverter model interpolates power dissipation from the LUTs to speed up the simulation...
Different models have been proposed for modeling the IV-characteristics of diodes. In this paper we present a simple model, which describes both the IV- and the temperature characteristics of a SOI-pin-diode and can be used for different diodes types. It is well known that the DC-characteristics of a diode can be approximated by the simple Shockley-equation. However, when a more exact modelling of...
Many electronic circuits and systems operating at low voltages are battery-powered. As a linear voltage regulator is used to this end, it has to be characterized by a high power efficiency, which can be achieved by a low voltage drop (LDO) across a pass element. In this paper a d.c. model of the voltage regulator LDO REG 104-5 V is presented. The theoretical considerations are illustrated by the results...
