Mathematical analysis to control power transfer in resonant power converters

This paper aims to present a mathematical analysis method for resonant power converter, in order to control the transfer of power which is transmitted to the load. Starting from the idea that most switching power converters are using the pulse width modulation (PWM) technique to control the switching elements, the paper presents an analysis of the control method that can be applied on such converters and a mathematical analysis of the resonant load that can be found at the output of the circuit. On the other hand, the paper proposes an interactive interface to design and simulate a resonant power converter. The tool can be used by experienced engineers in power converters domain, to properly configure such a circuit, but also by those who are starting to learn and understand how these circuits are working. The tool allows seeing, not just the final values for the components that make the circuit, but also the waveforms form the main components. By doing so, the converter´s area of operation can be observed, allowing to adjust the design in order to improve the design.
