Abstract The stability of the charger for charging current of the battery is one of the important indicators of the charging machine performance. The duty ratio to output transfer function was derived due to charger charging current control system of the small signal model. The PI controller was designed, and the correction system stability margin was analyzed, through the way of zero-pole assignment. The digital realization form of the PI controller was deduced, and the PI control program of Digital Signal Processor (DSP) was designed. Then, the performance of the design was verified by simulation and field test.
