Pulse Width Modulation to Control a Resonant Inverter

In this paper, a study was made of the control method for a resonant inverter with a multifunctional integral electromagnetic component (MIEC), which acts as an oscillatory circuit and at the same time a stabilizer. This makes it possible to improve the output parameters and the efficiency of electrical energy conversion. The main task is to obtain the results of computer simulation and their study. The authors developed a computer model in the Matlab environment and implemented pulse-width modulation (PWM) to control the output parameters of a resonant inverter based on MIEC. The effectiveness of this converter control method was also evaluated. The developed model provides the possibility of a deeper study of the characteristics of the system. The results confirm the improvement in the quality of the output parameters, the reduction of ripple. The range of regulation of the output voltage is increased due to the use of PWM, while maintaining high efficiency values.
