Abstract

This paper presents the analysis of dynamic response of the fuel cells, PWM implementation, and design of a closed-loop controller for a Z-source converter. For an electrical analysis of the fuel cell powered systems, the fuel cell is modeled by a R-C circuit including its voltage-current polarization curve. A discrete-time state space equation is given to implement digital control and a space vector pulse width modulation (SVPWM) technique is modified to realize the shoot-through zero vectors that boost the DC-link voltage. Also, two feedback controllers are designed to obtain a sinusoid AC voltage under linear/nonlinear loads: voltage controller in the outer loop and current controller in the inner loop.
