Abstract
The substantial increasing of switching devices utilization such as switching power converters, inverters, electronic ballast, UPS, and computer equipment, introduce harmonic distortion in supply systems because of their non-linear characteristics. The waveform distortion produces harmonics that not only increases power losses but also introduces a distortion power, which sums to time-average real and reactive power usually considered in linear circuits. Therefore, effects on harmonics must be considered in the circuit design. In this paper, the current distortion introduced by a Class-D full wave resonant rectifier used in a series-series compensation circuit for wireless power transfer is considered and a general approach to derive a rectifier equivalent impedance that consider the effect of distortion on the output power is presented.File | Dimensione | Formato | |
