Abstract
An energy storage apparatus has developed for railway vehicles by adopting a bidirectional DC-DC converter to increase the efficiency of charge/discharge, comprising that; a power receiving unit, filter unit, charging unit storage unit having a plurality of super-capacitors, capacitor monitoring unit, a plurality of bidirectional DC-DC converters arranged in parallel, and voltage detector electrically connected to the filter unit, current detector for detecting the currents flowing. The controller further comprises; an analog interface board, signal identifying board, signal control board, digital output contact unit, communicating board, PWM control board, optical output board, external gate driver. The PWM control board includes; a sensor input circuit, A/D converter, calculation unit, calculation control processor, and power monitoring unit. It is easy to add a storage unit including supercapacitor in a form of box module for increasing capacity and efficient of charging/discharging of the storage unit through various sensors and signal checking.
