The main purpose of this paper is to develop a DC voltage controller with AC power ripple compensation for single phase ACDC converter, which is served as the front-end converter for an energy storage system. Due to the single phase ACDC converter circuit topology, the AC and DC side both exist power ripple with doubled grid frequency. In conventional controller, DC voltage is controlled to be a constant...
This paper presents an acoustic-noise-reduction control using a random switching technique for front-end switch-mode rectifiers (SMRs) of a permanent-magnet synchronous-motor (PMSM) drive. First, the PMSM drive and its front-end ac-switch-based SMR are established. The proper controls are conducted to let the motor drive possess good driving characteristics. In the acoustic-noise-reduction control...
