Abstract

Multiple structured current-source converters are applied for a superconducting magnetic energy storage (SMES) system. Suitable control method and control block diagram are proposed by taking much use of the advantage of this multiple structure. A multi-modular pulse width modulation (PWM) control strategy of current-source converters for the purpose of higher efficiency and less harmonic distortion is developed with an idea for practical application. A design of a multi-reduced instruction set computer (RISC) controller is presented to put the proposed control blocks into practice. The results of the digital simulation by Electromagnetic Transients Program (EMTP) and the experimental results of the test module are provided to validate the proposed control method of SMES power conditioning
