Guest Editorial: Special Issue on Power Converters and Control Techniques for Very Fast Response Applications

Efficient power converters capable of changing their output voltage at very high speeds (submicrosecond scale) are mandatory for very fast response (VFR) applications. They are necessary to regulate loads that demand very fast voltage changes and to supply high-frequency-pulsed loads for data processing, communication, and portable equipment. VFR converters likewise become necessary for applications in which the efficient generation of high-frequency waveforms is mandatory: envelope amplifiers (EAs) for envelope tracking (ET) techniques, visible light communication (VLC) transmitters using light-emitting diodes (LEDs), switched-mode radio frequency power amplifiers and high-frequency inverters, among others.
