dc.description.abstractPurpose: To obtain the electrical load characteristic of alkaline electrolyzer that changes continuously with temperature for different operating conditions and to implement power control of the electrolyzer with the resonant converter to reduce the limitations of PWM switching at high switching frequencies. Theory and Methods: Experimental setup consisting of alkaline electrolyzer, the converter and the control circuit was established. The electrical load characteristic of the electrolyzer was obtained for different electrolyte temperatures, constant operating voltage and constant operating current. The closed-loop control of the system was carried out by proportional control. The amount of hydrogen produced for different electrolyte temperatures (40 degrees C and 50 degrees C) and nominal operating current (10 A) were calculated and approximately measured. The calculation and measurement results were presented comparatively in tables. Results and Conclusion: The current of electrolyzer must be controlled. The series resonant converter is suitable for applications with high input voltage and low output current, as the switching losses are reduced with decreasing the output current. In addition, the converter is simple in structure and easy to implement. For nominal operating current of electrolyzer, the efficiency and the switching frequency of the converter are 88% and 125 kHz, respectively. These efficiency and switching frequency values are higher than the efficiency and switching frequency value of insulated PWM converters realized for electrolysis applications. As a result of the calculations and measurements, it is observed that the energy, Faraday and cell efficiency of the electrolyzer are 80.05%, 74.47% and 59.61%, respectively. Moreover, these efficiency values increase with the increasing electrolyte temperature.en_US
