The series-resonant converter is one of the major classes of electronic power converters that are extensively applied in dc-dc conversion. This technology transfers bulk energy efficiently through a series-resonant circuit in the direct path of the energy transfer. This resonant converter forms a high-frequency ac link between the voltage sources connected to the input and output terminals. The high-frequency link is exploited in the application of a modulation process, thus avoiding the use of bulky and expensive, low-order harmonic filters. The achievable high-pulse repetition frequency is rooted in the efficient turn-off mechanism of the semiconductor switches and does not compromise their reliability. The classical objective of an ac-dc converter is to control the (average value of the) output waveform (often the output voltage). The resolution of the high-frequency input current of the series-resonant converter introduces the possibility of accurately controlling the waveform of the source current. In combination with the accurate positioning of the high-frequency current pulses, it is possible to influence the exchange of power with the source by the introduced method of active filtering. A power factor equal to one would lead to optimal operation.
