A synchronous machine used to convert alternating current (ac) to direct current (dc), or vice versa. The ac-to-dc converter has been superseded by solid-state converters using silicon controlled rectifiers (SCRs) or power MOSFETs (for reasons of efficiency, lower maintenance costs, and less trouble) or by motor-generator sets. Converters are no longer manufactured, but there are converters still in use. See also: Power integrated circuits; Semiconductor rectifier
