Abstract


Vertical lift elevator in the process, due to widely varying power , energy-saving potential. This major work is to combine the characteristics of the elevator system , super capacitor energy storage system for super capacitor capacity requirements and other relevant parameters are discussed in detail settings . Also ancillary bidirectional DC / DC converter studied. Based on the study of the structure and operation of the elevator based on the characteristics of its energy state during operation changes in a detailed analysis of the energy storage device to obtain the super capacitor capacity calculation method , and on this basis , according to the super- capacitor capacity requirements and system -level bi-directional converter power before the relationship , a set of simple and effective energy management programs to reduce the super capacitor energy storage device capacity requirements . And for super capacitor capacity setting gives a general principle. Energy storage devices and systems required between the DC bus bidirectional converter for energy transfer , this bi-directional DC converter topology for a variety of advantages and disadvantages are compared , combined with super-capacitor energy storage device in the specific application needs, come BUCK / BOOST -type converter is more suitable for this application . This article is designed for the energy storage device based on DSP ( Digital Signal Processor ) digital control works with a variety of bi-directional DC / DC converter for low-power prototype, the capacitor discharge, constant current mode to the DC bus transporting energy ; the capacitor is charging, a piecewise constant current mode or voltage mode for charging. The paper gives a detailed hardware circuit and a digital control part of the design process and verified by experiment .
