164. What type of electric propulsion system converter is shown in the illustration
The illustration depicts a three-phase AC supply, controlled rectifier, DC link, controlled inverter, and AC synchronous motor, which defines a synchroconverter used for electric propulsion. This AC-DC-AC conversion system utilizes a rectifier, DC link, and inverter to provide variable-frequency power to a synchronous motor, distinguishing it from cycloconverters (direct AC-to-AC conversion), controlled rectifier converters (lacking an inverter), and PWM converters (characterized by high-frequency switching).
