Abstract
Abstract: In order to solve the problem of complicated and costly on-line impedance monitoring operation of vehicle fuel cells, a test method that can obtain the electrochemical impedance spectroscopy (EIS) of fuel cell by Fourier transformation against output voltage and output current of fuel cell through DC/DC generation of micro-current signal is proposed. This method is integrated in a cascaded system of parallel Boost and DC/AC/DC. The parallel Boost can realize the decoupling of power transmission and disturbance signal, the DC/AC/DC converters can achieve higher boost ratios, which makes the test system more suitable for higher voltage levels such as fuel cell vehicles. Simulation results built in MATLAB show that this system can achieve high voltage ratio, and its current ripple injection has little influence upon system and can measure the accurate internal resistance value.
