The ride-through capability of adjustable-speed drives has become an important issue due to its direct impact on production and revenue losses. This paper presents a ride-through strategy for matrix-converter (MC) adjustable-speed drives, aimed at addressing the vulnerability of these systems to voltage sags, which are the main cause of converter tripping. The methodology involves a reduced speed/load approach that enforces constant volts/hertz operation, regulating the modulation index of the matrix converter to counteract supply voltage drops and reducing the speed reference when necessary. The strategy is designed to maintain future torque capability and reduce motor load similarly to conventional drives. Additionally, it minimizes acceleration for sensitive equipment post-disturbance, enhancing overall operation reliability. Experimental validation was conducted using a TMS320C32 DSP-based system under typical industrial disturbances, including three-phase and single-phase sags varying from 60% to 60%. The results illustrate the effectiveness of the proposed strategy, highlighting its suitability for both variable and constant torque loads.
