According to the character non-linear of the fuel cell power plant inverter system ,the linear treatment is taken and digital PI control of the output waveform is proposed.The voltage instantaneous feedback control strategy with filter in-ductor current inside loop is used to improve dynamic-state response and steady precision separately.The PI parameters are designed by trial and assemble method with TI controller software platform together.The experiments show that the de-sign is effective,and efficient,and the voltage output waveform is good.
