Résumé: | Water is a crucial resource that has been experiencing a continuous decline in quality over the years. Therefore, treating water has become a top priority, and the need to respect it has been recognized since ancient times. UV-c technology is an excellent solution that addresses both of these requirements effectively. The concept of UV bactericidal treatment involves the generation of ultraviolet rays inside a treatment chamber containing water. To ensure the effectiveness of UV-c disinfection, it is crucial to provide a reliable power supply to the low-pressure mercury-argon discharge lamps. In this research, the main objective is to determine the most optimal power source. To achieve this goal, the discharge lamp-electronic ballast system will be powered by three different types of converters. The first power supply utilizes a conventional converter, consisting of a half-bridge rectifier and inverter with PWM control. The second power supply employs a 4-cell serial multicell converter, which adopts a control strategy that modulates duty cycles. The third power supply is based on a single-phase matrix converter. In order to achieve the desired amplitude and frequency, a linear adjustment of the current is applied using a PI regulator. This approach aims to improve the quality of the current waveform and reduce total harmonic distortion (THD). The simulations for these power supply configurations were conducted using Matlab/Simpower system. |
