The authors propose a new power consolidation-inversion-control system for the Faraday MHD generator using the voltage source PWM inverters. The d. c. output power from each electrodes pair of MHD generator is at first inverted into three phase a. c. power by voltage source PWM inverter and then the a. c. powers are consolidated by transformers. The proposed system does not need expensive equipments of a. c. filter and phase modifier and can independently and simultaneously control the active and reative powers provided to the electric power system. Numerical simulations of the whole system including the Faraday MHD generator, the proposed power consolidation-inversion-control system and the electric power system show that the proposed system can stably and steadily transmit and control the electric power from MHD gnerator to electric power system. It is also confirmed that the proposed system can independently and simultaneously control the active and reactive powers and can be used as a fast power controller.
