Power electronic technology has been widely employed in renewable energy systems, like photovoltaic(PV) generation systems, wind generation systems; in home appliances, like compact fluorescent lamps (CFLs), LED lamps, microwaves. However, power electronic based devices are harmonic polluters, which could inject a relatively large amount of harmonics into the power grid relative to their power demand...
This paper presents a novel formulation for the inverse class-F mode of operation, termed the “continuous inverse class-F mode”, resulting in an extended or continuous set of ‘allowed’ current waveforms. In comparison to the classical inverse class-F mode, this approach provides a much wider design space for the realization of broadband power amplifiers, where output performance can be maintained...
Class D amplifiers are becoming the most feasible solution for embedded audio application. However, distortions due to the non-linear nature of switching stage are the main drawback for this amplifier topology. This paper discusses the design and implementation of high fidelity audio class D using sliding mode control scheme. This design method proves to be a cost effective solution for industrial...
