The design of converter circuit in distributed power generation system

With the micro-turbine technology continues to improve, Micro-Turbine Generator(MTG) has become the most mature and most competitive business in distributed power generation equipment. This article designed a converter circuit that applied to distributed power generation system by micro-turbine drived a high-speed motor. PWM rectifier and PWM inverter can use the same topology for the whole system design. Space vector pulse width modulation(SVPWM) control algorithm is applied to this converter. A simulation model of converter circuit system applied to distributed generation can be designed. The simulation results show the feasibility of the proposed structure and the control strategy. Using SVPWM control method can improve the utilization ratio of direct current voltage and is easy-to-digital realization. It reduce harmonic currents and loss of the generator and improve system stability.
