Analysis of the ultracapacitor module in power buffering

چکیده
This paper presents efficiency analysis of the power buffering in common voltage bus systems. Operation of the power buffering is briefly described with the power control experiments. The efficiency measurement setup and performed measurements from the charging and discharging events of the ultracapacitor module with the dc-dc converter are presented. As a result, the efficiency map of the dc-dc converter is gained and losses of the ultracapacitor module energy storage are differentiated. In addition, the efficiency map of the full charging and discharging cycle of the energy storage system is attained and the capacitance variation of the ultracapacitor module in the dc-dc converters operation area is presented. The operation areas of the energy storage system and variable speed diesel generator (VSDG) in series hybrid electric vehicle (SHEV) application are investigated in simulation case studies.

متن کاملDevelopment of a Current Control Ultracapacitor Charger Based on Digital Signal Processing
Ultracapacitor usually use as a short-term duration electrical energy storage because it has several advantages, like high power density (5kW/kg), long lifecycle and very good charge/discharge efficiency. Unlike batteries, ultracapacitors may be charged and discharged at similar rates. This is very useful in energy recovery systems such as dynamic braking of transport systems. Here are a few ch...
