Abstract

Abstract:
The paper describes the possible sources of electrical energy for military purposes, deals
with the necessity of electrical energy accumulation and gives brief analysis of different
types of energy buffers, namely electrolytic capacitors, accumulators (batteries) and
supercapacitors. Dynamical properties of developed electrical energy generation set
with the variable speed-constant frequency technology have been analysed with respect
to the effect of sudden extreme load increase. At low speeds the driving engine is
overloaded and generator is not able to deliver sufficient peak energy. Supercapacitor as
the controlled energy buffer in cooperation with respective DC/DC bi-directional
converter and AC/DC/AC combined converter solves the problem. Results of
measurements and verification of reliable system operation proving the credibility of
performed analyses and calculations are discussed in the paper conclusions.
