FFC-NMR power supply with hybrid controlo of the semiconductor devices. Journal of Low Power Electronics and Applications, 13(3), 1-10. https://doi.org/10.3390/jlpea13030052http://hdl.handle.net/10400.21/22106The performance of FFC-NMR power supplies is evaluated not only considering the technique requirements but also comparing efficiencies and power consumption. Since the characteristics of FFC-NMR power supplies depend on the power circuit topology and on the control solutions, the control design is a core aspect for the development of new FFC systems. A new hybrid solution is described that allows controlling the power of semiconductors by switches (ON/OFF mode) or as a linear device. The approach avoids over-design of the power supply and makes it possible to implement new low power solutions constituting a novel design by joining a continuous match between the ON/OFF mode and the linear control of the power semiconductor devices.engPower supplySemiconductor devicesNMRUpward transientDownward transientHybrid controlresearch articlehttps://doi.org/10.3390/jlpea130300522079-9268
