Single Phase Controlled Rectifier using TN3050H-12 Thyristor and VSE5PX3012 Diode: Power Control and Energy Efficiency in Marine Applications

Abstract

This paper is the result of research on the application of a single-phase controlled rectifier using TN3050H-12LY type thyristor and VS-E5PX3012 type diode, focusing on its application in an electric propulsion system for ships. This rectifier allows precise control of the DC power supplied to the load, optimizing the performance of the propulsion motor while increasing energy efficiency. This paper provides detailed calculations for the output DC voltage, power control through phase angle modulation, system efficiency, and thermal management. The simulation results with an AC voltage of 400 V, 50 Hz with the rectifier system and components used are capable of producing voltages up to 360 Volts DC and can deliver electrical power of around 12 kW with a variation in the trigger angle and an efficiency of around 90% in its working area.
