Featured Application: DC/DC converters design and teaching.Abstract: By the application of well-known circuit analysis techniques, this paper develops an intuitive approach to model the steady state regime of the three DC/DC power converters' basic topologies (buck, boost and buck-boost). The developed approach can be considered new, realistic, accurate, general and practical. The approach is new because it is not present in the literature; realistic because it considers the main non-idealities of the different passive and active components that make up the converters; accurate because its theoretical results fit properly to those obtained in actual converters; general because it is valid for the three basic topologies; and practical because its applicability is easy and immediate from the data sheets of the converters' components (no measurements are needed). The developed model transforms a complex system with strong non-idealities in the form of distributed parameters, in a simple and intuitive scheme of concentrated parameters (just three), which accurately reflects the actual behavior of the three basic converters' topologies. The characteristic parameters of the model and its main relationships are determined analytically. The quality of the developed approach has been tested in the paper and can be considered excellent.

“…This approach adds additional complexity and cost to the system due to non-standard stack voltages and low volume production. A comprehensive design to minimise the costs of such a system has been undertaken [10], with a lot of work concentrating on electronically interfacing hydrogen fuel cells as seen in [11], [12], [13]. The use of an energy management system and minimising the number of times energy is converted between AC and DC is of upmost importance in improving the efficiency of a system [14].…”

Hybrid power infrastructure is often viewed as an alternative system configuration for off-grid telecom base stations. These systems are used to reduce the fuel consumption of diesel generator sites and often rely on wind or solar to supplement some of the power to the load. The ability of a site to use the renewable energy efficiently becomes more critical on sites where the quality of the wind or solar resource is poor or highly variable. The long term and short term effects of wind and solar power contributions to the system are demonstrated using historical wind speed/solar irradiation data over a 3 year period. A feasible approach is proposed to improve the efficiency of the system by analysing the rate of change of the renewable energy source(s). Using several successive measurements, the battery charging system can be restrained temporarily to allow for the initial stages of diurnal weather patterns. These patterns may later negate the need for the charging cycle which can result in wasted power should a renewable power source increase its power output during a generator charging cycle.
