The private power producers are increasing rapidly to meet rising load demand in domestic. commercial. and industrial sectors. In this scenario. the distributed generation systems (DGs) play an important role over fossil fuel generation. Among different distributed generation technologies such as fuel cell. wind power. and solar. the fuel-cell-based distributed generation is becoming more popular due to its high efficiency. cleanliness. modularity. and cost effectiveness. The development of a suitable power electronic interface and control schemes. therefore. play vital role in regulating fuel-cell voltage. both under steady and transient conditions. This paper. therefore. presents a DSP-controlled single stage power electronic interface for fuel-cell-based generation intended for residential grid connected applications. The presented scheme generates pulse width modulation (PWM) control signals using TMS320F2812 DSP controller interfaced with MATLAB Simulink model. A comprehensive simulink based model of the scheme is evolved and discussed. The experimental results are presented for varying loads and transient conditions.
